MuniEnhanced Fund, Inc.

The Benefits and Risks of Leveraging

MuniEnhanced Fund, Inc. utilizes leveraging to seek to enhance the yield and net
asset value of its Common Stock. However, these objectives cannot be achieved in
all interest rate environments. To leverage, the Fund issues Preferred Stock,
which pays dividends at prevailing short-term interest rates, and invests the
proceeds in long-term municipal bonds. The interest earned on these investments,
net of dividends to Preferred Stock, is paid to Common Stock shareholders in the
form of dividends, and the value of these portfolio holdings is reflected in the
per share net asset value of the Fund's Common Stock. However, in order to
benefit Common Stock shareholders, the yield curve must be positively sloped;
that is, short-term interest rates must be lower than long-term interest rates.
At the same time, a period of generally declining interest rates will benefit
Common Stock shareholders. If either of these conditions change, then the risks
of leveraging will begin to outweigh the benefits.

To illustrate these concepts, assume a fund's Common Stock capitalization of
$100 million and the issuance of Preferred Stock for an additional $50 million,
creating a total value of $150 million available for investment in long-term
municipal bonds. If prevailing short-term interest rates are approximately 3%
and long-term interest rates are approximately 6%, the yield curve has a
strongly positive slope. The fund pays dividends on the $50 million of Preferred
Stock based on the lower short-term interest rates. At the same time, the fund's
total portfolio of $150 million earns the income based on long-term interest
rates. Of course, increases in short-term interest rates would reduce (and even
eliminate) the dividends on the Common Stock.

In this case, the dividends paid to Preferred Stock shareholders are
significantly lower than the income earned on the fund's long-term investments,
and therefore the Common Stock shareholders are the beneficiaries of the
incremental yield. However, if short-term interest rates rise, narrowing the
differential between short-term and long-term interest rates, the incremental
yield pickup on the Common Stock will be reduced or eliminated completely. At
the same time, the market value on the fund's Common Stock (that is, its price
as listed on the New York Stock Exchange), may, as a result, decline.
Furthermore, if long-term interest rates rise, the Common Stock's net asset
value will reflect the full decline in the price of the portfolio's investments,
since the value of the fund's Preferred Stock does not fluctuate. In addition to
the decline in net asset value, the market value of the fund's Common Stock may
also decline.

As a part of its investment strategy, the Fund may invest in certain securities
whose potential income return is inversely related to changes in a floating
interest rate ("inverse floaters"). In general, income on inverse floaters will
decrease when short-term interest rates increase and increase when short-term
interest rates decrease. Investments in inverse floaters may be characterized as
derivative securities and may subject the Fund to the risks of reduced or
eliminated interest payments and losses on invested principal. In addition,
inverse floaters have the effect of providing investment leverage and, as a
result, the market value of such securities will generally be more volatile than
that of fixed rate, tax-exempt securities. To the extent the Fund invests in
inverse floaters, the market value of the Fund's portfolio and the net asset
value of the Fund's shares may also be more volatile than if the Fund did not
invest in these securities. As of July 31, 2004, the percentage of the Fund's
total net assets invested in inverse floaters was 10.20%, before the deduction
of Preferred Stock.

Swap Agreements

The Fund may also invest in swap agreements, which are over-the-counter
contracts in which one party agrees to make periodic payments based on the
change in market value of a specified bond, basket of bonds, or index in return
for periodic payments based on a fixed or variable interest rate or the change
in market value of a different bond, basket of bonds or index. Swap agreements
may be used to obtain exposure to a bond or market without owning or taking
physical custody of securities. Swap agreements involve the risk that the party
with whom the Fund has entered into the swap will default on its obligation to
pay the Fund and the risk that the Fund will not be able to meet its obligations
to pay the other party to the agreement.

A Letter From the President

Dear Shareholder

In recent months, the Federal Reserve Board (the Fed) has taken center stage as
it shifts away from its long-accommodative monetary stance. In a
much-anticipated move, the Fed raised the Federal Funds rate 25 basis points
(.25%) on June 30, representing the first interest rate increase in four years.
Shortly after period-end, the Fed announced an additional 25 basis point rate
hike, bringing the target short-term interest rate to 1.50% -- still low by
historical standards. The Fed has been very deliberate in telegraphing its
intention to take a "measured" approach to the interest rate increases so as to
avoid upsetting the economy or the financial markets. Still, the Fed has stated
that it may move more aggressively if inflation and economic growth accelerate
more than anticipated. In addition to the Fed policy change, the financial
markets recently have had to grapple with a tense geopolitical environment,
higher oil prices and the worry and anticipation that accompanies a presidential
election.

While inflation has moved up on a cyclical basis, this is an indication that the
Fed has been successful in avoiding deflation -- just as it set out to do a year
ago. The challenge now is to normalize interest rates in order to keep inflation
within acceptable limits. The futures curve currently projects further increases
in short-term interest rates before year-end.

The transition to higher rates can cause concern among equity and fixed income
investors alike. For bond investors, rising rates means the value of older
issues declines because they bear the former lower rates. In addition,
increasing inflation erodes the purchasing power of fixed income securities. But
because municipal bonds offer the advantage of tax-exempt income, they continue
to be an attractive alternative for many fixed income investors. For the
six-month and 12-month periods ended July 31, 2004, municipal bonds posted
returns of +.06% and +5.79%, respectively, as measured by the Lehman Brothers
Municipal Bond Index.

As always, our investment professionals are closely monitoring the markets, the
economy and the overall environment in an effort to make well-informed decisions
for the portfolios they manage. Our goal is to provide shareholders with
competitive returns, while always keeping one eye on managing the unavoidable
risk inherent in investing.

We thank you for trusting Merrill Lynch Investment Managers with your investment
assets, and we look forward to serving you in the months and years ahead.

                                        Sincerely,


                                        /s/ Terry K. Glenn

                                        Terry K. Glenn
                                        President and Director

A Discussion With Your Fund's Portfolio Manager

      We maintained our focus on seeking to enhance yield and protect the Fund's
net asset value in anticipation of rising interest rates.

Discuss the recent market environment relative to municipal bonds.

Long-term U.S. Treasury bond yields ended the period higher than where they
started, although the rise was not uninterrupted. Early in the period, bond
yields actually declined as prices -- which move in the opposite direction --
rose. Despite continued improvement in U.S. economic conditions, solid job
creation remained elusive. Consumer confidence faltered, and investors became
increasingly convinced that the Federal Reserve Board (the Fed) would hold
short-term interest rates at their historic lows. Under the circumstances,
long-term U.S. Treasury bond yields fell to 4.65% by mid-March 2004.

Beginning in early April, however, monthly employment reports began to show
unexpectedly large gains. In response, bond prices fell (yields increased).
Associated improvements in consumer confidence and spending led some investors
to reverse their earlier expectations, believing instead that the Fed would soon
be forced to raise short-term interest rates to ward off potential inflation. By
early June, long-term U.S. Treasury bond yields had risen to over 5.50%.

For the remainder of the period, bond yields generally declined. While economic
growth remained positive, inflationary measures continued to be negligible. More
importantly, on June 30, the Fed raised its short-term interest rate target for
the first time in four years -- from 1% to 1.25%. In doing so, the Fed indicated
a tendency toward a measured, moderate monetary tightening cycle, which helped
support higher bond prices (and lower yields). Nevertheless, by July 31, U.S.
Treasury bond yields stood at 5.20%, representing an increase of nearly 25 basis
points (.25%) over the past six months. The 10-year U.S. Treasury note yield was
4.48%, an increase of 35 basis points during the period.

Yields on tax-exempt bonds generally followed those of their taxable
counterparts higher over the past six months. Long-term revenue bond yields, as
measured by the Bond Buyer Revenue Bond Index, rose approximately 30 basis
points during the period to 5.31%. According to Municipal Market Data, yields on
AAA-rated issues maturing in 30 years increased nearly 30 basis points to 4.91%
at July 31, while 10-year AAA-rated issues saw their yields increase 25 basis
points to 3.79%.

During the past six months, approximately $195 billion in new long-term
tax-exempt bonds was underwritten, a decline of more than 6% versus the same
period a year ago. Approximately $100 billion in long-term tax-exempt bonds was
issued in the last three months of the period, a decline of more than 15%
compared to the same time last year. While recent declines in municipal bond
issuance have lent support to the tax-exempt bond market's technical position,
retail investor demand has diminished somewhat in recent months. Low nominal
municipal bond yields and summer seasonal factors have resulted in sizable
tax-exempt mutual fund outflows during the period. Nevertheless, we expect that
higher nominal bond yields in the months ahead should trigger increased investor
demand, while manageable new-issue volume continues to support the tax-exempt
market's technical position.

How did the Fund perform during the period in light of the existing market
conditions?

For the six-month period ended July 31, 2004, the Common Stock of MuniEnhanced
Fund, Inc. had net annualized yields of 6.46% and 7.06%, based on a period-end
per share net asset value of $11.37 and a per share market price of $10.39,
respectively, and $.366 per share income dividends. Over the same period, the
total investment return on the Fund's Common Stock was -.53%, based on a change
in per share net asset value from $11.83 to $11.37, and assuming reinvestment of
$.366 per share ordinary income dividends.

The Fund's total return, based on net asset value, was comparable to that of the
Lipper Insured Municipal Debt Funds (Leveraged) category, which had an average
return of -.61% for the six-month period ended July 31, 2004. (Funds in this
Lipper category invest primarily in municipal debt issues insured as to timely
payment. These funds can be leveraged via use of debt, preferred equity and/or
reverse repurchase agreements.) The Fund's defensive positioning benefited its
relative performance as interest rates headed higher. Our shorter-than-average
duration meant that the Fund was subject to less volatility than many of its
peers when interest rates increased, albeit modestly, during the period.
Offsetting the benefits of our defensive positioning was the underperformance of
certain Fund holdings in the past six months.


4            MUNIENHANCED FUND, INC.               JULY 31, 2004


Importantly, the Fund maintained a competitive yield and increased its dividend
during the period to $.061 per share.

For the six-month period ended July 31, 2004, the Fund's Auction Market
Preferred Stock (AMPS) had average yields as follows: Series A, .91%; Series B,
..97%; and Series C, .96%.

For a description of the Fund's total investment return based on a change in the
per share market value of the Fund's Common Stock (as measured by the trading
price of the Fund's shares on the New York Stock Exchange), and assuming
reinvestment of dividends, please refer to the Financial Highlights section of
this report. As a closed-end fund, the Fund's shares may trade in the secondary
market at a premium or discount to the Fund's net asset value. As a result,
total investment returns based on changes in the market value of the Fund's
Common Stock can vary significantly from total investment returns based on
changes in the Fund's net asset value.

What changes were made to the portfolio during the period?

We did not make any significant changes to the portfolio or our investment
strategy over the past six months. Given the steepness of the yield curve, we
continued to favor premium-coupon bonds in the 25-year maturity range. We sought
to sell bonds in the intermediate maturity range -- that is, those maturing in
10 years - 15 years. This proved to be the most volatile part of the yield
curve. The municipal yield curve flattened out past the 25-year range;
therefore, there was no significant yield to be gained by extending much further
out.

In addition, we were able to take advantage of heavy supply and relatively
inexpensive prices in adding some more California municipal bonds to the
portfolio. The goal is to achieve relative outperformance on these bonds when
conditions improve in the state and prices return to their historically higher
levels. In fact, we are already seeing evidence of this as the state's financial
picture begins to strengthen. Moody's Investor Service upgraded its rating on
California general obligation bonds during the period, bringing the rating from
Baa1 to A3.

We maintained the Fund's defensive market posture throughout the period in
recognition of certain robust economic indicators and the Fed's stated intention
to continue raising interest rates. A defensive stance on interest rates should
help us protect the portfolio's value as interest rates rise. Finally, we
generally maintained the Fund's fully invested position in an effort to enhance
shareholder income. With short-term interest rates still at historic lows, the
cost of holding cash reserves would have been relatively high.

Given the low short-term interest rates, the Fund's borrowing costs remained at
attractive levels of around 1% - 1.25%. These levels, in combination with a
positively sloped yield curve, provided a generous income benefit to the Common
Stock shareholders from the leveraging of Preferred Stock. We believe the Fund's
borrowing costs should remain at relatively low levels through the next period
as the Fed pursues its measured approach to interest rate increases. However,
should the spread between short-term and long-term interest rates narrow, the
benefits of leveraging will decline and, as a result, reduce the yield on the
Fund's Common Stock. At the end of the period, the Fund's leverage amount, due
to AMPS, was 31% of total net assets. (For a more complete explanation of the
benefits and risks of leveraging, see page 2 of this report to shareholders.)

How would you characterize the Fund's position at the close of the period?

At the end of the period, the portfolio remained essentially fully invested in
high-quality municipal bonds. We believe this positioning should continue to
provide a material benefit to the Common Stock shareholder as short-term
interest rates remain relatively low. The Fund also remained overweight in
premium-coupon bonds, particularly those with maturities in the 25-year range.

We believe our defensive position prepares the Fund for strong relative
performance in a stable to rising interest rate environment. In fact, that is
what we expect to see in the months ahead as the Fed continues tightening
monetary policy, but with caution. As always, we will continue to monitor the
Fed's language, payroll reports, inflation data and other important economic
indicators in order to make the most informed decisions in managing the
portfolio.

Notes to Financial Statements

1. Significant Accounting Policies:

MuniEnhanced Fund, Inc. (the "Fund") is registered under the Investment Company
Act of 1940, as amended, as a non-diversified, closed-end management investment
company. The Fund's financial statements are prepared in conformity with U.S.
generally accepted accounting principles, which may require the use of
management accruals and estimates. Actual results may differ from these
estimates. These unaudited financial statements reflect all adjustments, which
are, in the opinion of management, necessary to present a fair statement of the
results for the interim period. All such adjustments are of a normal, recurring
nature. The Fund determines and makes available for publication the net asset
value of its Common Stock on a daily basis. The Fund's Common Stock is listed on
the New York Stock Exchange under the symbol MEN. The following is a summary of
significant accounting policies followed by the Fund.

(a) Valuation of investments -- Municipal bonds are traded primarily in the
over-the-counter markets and are valued at the last available bid price in the
over-the-counter market or on the basis of yield equivalents as obtained by the
Fund's pricing service from one or more dealers that make markets in the
securities. Financial futures contracts and options thereon, which are traded on
exchanges, are valued at their closing prices as of the close of such exchanges.
Options written or purchased are valued at the last sale price in the case of
exchange-traded options. In the case of options traded in the over-the-counter
market, valuation is the last asked price (options written) or the last bid
price (options purchased). Swap agreements are valued by quoted fair values
received daily by the Fund from the counterparty. Short-term investments with a
remaining maturity of sixty days or less are valued at amortized cost, which
approximates market value. Securities and assets for which market quotations are
not readily available are valued at fair value as determined in good faith by or
under the direction of the Board of Directors of the Fund, including valuations
furnished by a pricing service retained by the Fund, which may utilize a matrix
system for valuations. The procedures of the pricing service and its valuations
are reviewed by the officers of the Fund under the general supervision of the
Board of Directors.

(b) Derivative financial instruments -- The Fund may engage in various portfolio
investment strategies both to increase the return of the Fund and to hedge, or
protect, its exposure to interest rate movements and movements in the securities
markets. Losses may arise due to changes in the value of the contract or if the
counterparty does not perform under the contract.

o     Financial futures contracts -- The Fund may purchase or sell financial
      futures contracts and options on such futures contracts. Futures contracts
      are contracts for delayed delivery of securities at a specific future date
      and at a specific price or yield. Upon entering into a contract, the Fund
      deposits and maintains as collateral such initial margin as required by
      the exchange on which the transaction is effected. Pursuant to the
      contract, the Fund agrees to receive from or pay to the broker an amount
      of cash equal to the daily fluctuation in value of the contract. Such
      receipts or payments are known as variation margin and are recorded by the
      Fund as unrealized gains or losses. When the contract is closed, the Fund
      records a realized gain or loss equal to the difference between the value
      of the contract at the time it was opened and the value at the time it was
      closed.

o     Options -- The Fund may write covered call options and purchase call and
      put options. When the Fund writes an option, an amount equal to the
      premium received by the Fund is reflected as an asset and an equivalent
      liability. The amount of the liability is subsequently marked-to-market
      reflecting the current market value of the option written. When a security
      is purchased or sold through an exercise of an option, the related premium
      paid (or received) is added to (or deducted from) the basis of the
      security acquired or deducted from (or added to) the proceeds of the
      security sold. When an option expires (or the Fund enters into a closing
      transaction), the Fund realizes a gain or loss on the option to the extent
      of the premiums received or paid (or gain or loss to the extent the cost
      of the closing transaction exceeds the premium paid or received).

      Written and purchased options are non-income producing investments.

o     Forward interest rate swaps -- The Fund may enter into forward interest
      rate swaps. In a forward interest rate swap, the Fund and the counterparty
      agree to make periodic net payments on a specified notional contract
      amount, commencing on a specified future effective date, unless terminated
      earlier. When the agreement is closed, the Fund records a realized gain or
      loss in an amount equal to the value of the agreement.

Notes to Financial Statements (concluded)

(c) Income taxes -- It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no federal income tax provision is required.

(d) Security transactions and investment income -- Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Realized gains and losses on security transactions are determined on the
identified cost basis. Dividend income is recorded on the ex-dividend dates.
Interest income is recognized on the accrual basis. The Fund amortizes all
premiums and discounts on debt securities.

(e) Dividends and distributions -- Dividends from net investment income are
declared daily and paid monthly. Distributions of capital gains are recorded on
the ex-dividend dates.

2. Investment Advisory Agreement and Transactions with Affiliates:

The Fund has entered into an Investment Advisory Agreement with Fund Asset
Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc.
("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML
& Co."), which is the limited partner.

FAM is responsible for the management of the Fund's portfolio and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operations of the Fund. For such services, the Fund pays a monthly fee at
an annual rate of .50% of the Fund's average daily net assets, including assets
acquired from the issuance of Preferred Stock. For the six months ended July 31,
2004, FAM reimbursed the Fund in the amount of $7,025.

For the six months ended July 31, 2004, the Fund reimbursed FAM $5,361 for
certain accounting services.

Certain officers and/or directors of the Fund are officers and/or directors of
FAM, PSI, and/or ML & Co.

3. Investments:

Purchases and sales of investments, excluding short-term securities, for the six
months ended July 31, 2004 were $95,822,473 and $81,031,699, respectively.

4. Stock Transactions:

The Fund is authorized to issue 200,000,000 shares of stock, par value $.10 per
share, all of which were initially classified as Common Stock. The Board of
Directors is authorized, however, to reclassify any unissued shares of stock
without the approval of the holders of Common Stock.

Preferred Stock

Auction Market Preferred Stock ("AMPS") are shares of Preferred Stock of the
Fund, with a par value of $.025 per share and a liquidation preference of
$25,000 per share, plus accrued and unpaid dividends, that entitle their holders

Dividend Policy

The Fund's dividend policy is to distribute all or a portion of its net
investment income to its shareholders on a monthly basis. In order to provide
shareholders with a more stable level of dividend distributions, the Fund may at
times pay out less than the entire amount of net investment income earned in any
particular month and may at times in any particular month pay out such
accumulated but undistributed income in addition to net investment income earned
in that month. As a result, the dividends paid by the Fund for any particular
month may be more or less than the amount of net investment income earned by the
Fund during such month. The Fund's current accumulated but undistributed net
investment income, if any, is disclosed in the Statement of Net Assets, which
comprises part of the financial information included in this report.

MuniEnhanced Fund, Inc. seeks to provide shareholders with as high a level of
current income exempt from federal income taxes as is consistent with its
investment policies by investing primarily in a portfolio of long-term,
investment grade municipal obligations, the interest on which is exempt from
federal income taxes in the opinion of the bond counsel to the issuer.

This report, including the financial information herein, is transmitted to
shareholders of MuniEnhanced Fund, Inc. for their information. It is not a
prospectus. Past performance results shown in this report should not be
considered a representation of future performance. The Fund has leveraged its
Common Stock and intends to remain leveraged by issuing Preferred Stock to
provide the Common Stock shareholders with a potentially higher rate of return.
Leverage creates risks for Common Stock shareholders, including the likelihood
of greater volatility of net asset value and market price of shares of the
Common Stock, and the risk that fluctuations in the short-term dividend rates of
the Preferred Stock may affect the yield to Common Stock shareholders.
Statements and other information herein are as dated and are subject to change.
