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

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

A Letter to Shareholders

Dear Shareholder

As the July reporting period closed, financial markets were rattled by ongoing
problems in the credit markets, particularly those associated with the subprime
mortgage industry. While this has been an issue for much of 2007, recent
headlines and some high-profile credit collapses reignited concerns that credit
problems could spill over into the broader economy and derail global financial
markets. Although volatility has reared its head throughout the year, the
fundamental market and economic backdrop has been little changed. U.S. economic
activity has decelerated, led by a slowdown in the housing market, but economies
outside the United States remain robust, which has been a boon for U.S. exports.
Through July, the Federal Reserve Board had kept the target short-term interest
rate on hold at 5.25%.

For the most part, equities continued to find support in robust
merger-and-acquisition activity, a healthy global economy, tame inflation,
relatively low interest rates, still-positive earnings growth and attractive
valuations. These tailwinds generally prevailed over such headwinds as the
weakening U.S. economy, slowing housing market, escalating geopolitical concerns
and high energy prices, leading the Standard & Poor's (S&P) 500 Index and the
Dow Jones Industrial Average to post new record highs in mid-July before
succumbing to the latest market correction.

Meanwhile, mixed economic signals and the credit market debacle have made for a
volatile backdrop for fixed income, with investors fleeing from bonds associated
with the housing and credit markets in favor of higher-quality Treasury bonds.
As a result, the 10-year Treasury yield, which touched 5.30% in June (its
highest level in five years), fell to nearly 4.75% by period-end. Prices
correspondingly rose, reflecting the investor flight to quality. Against this
backdrop, financial markets posted mixed results for the six-month period ended
July 31, 2007, but continued to exhibit relative strength when measured over the
past year:

The Benefits and Risks of Leveraging

BlackRock 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 of July 31, 2007, the Fund's leverage amount, due to Auction Market Preferred
Stock, was 36.02% of total net assets, before the deduction of Preferred Stock.

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. (See Note 1(c) to Financial Statements for details
of municipal bonds held in trust.)

Swap Agreements

The Fund may 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.

Notes to Financial Statements (Unaudited)

1. Significant Accounting Policies:

BlackRock 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
shares are 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 ("OTC") markets and are valued at the last available bid price
in the OTC market or on the basis of values as obtained by a pricing service.
Pricing services use valuation matrixes that incorporate both dealer-supplied
valuations and valuation models. The procedures of the pricing service and its
valuations are reviewed by the officers of the Fund under the general direction
of the Board of Directors. Such valuations and procedures are reviewed
periodically by the Board of Directors of the Fund. 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 OTC market, valuation is the last asked price
(options written) or the last bid price (options purchased). Swap agreements are
valued by quoted fair valuations received daily by the Fund's pricing service.
Investments in open-end investment companies are valued at their net asset value
each business day. Securities and other 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. Such valuations and
procedures will be reviewed periodically by the Board of Directors of the Fund.

(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 due to an
unfavorable change in the underlying security or index, or if the counterparty
does not perform under the contract. The counterparty for certain instruments
may pledge cash or securities as collateral.

o     Financial futures contracts -- The Fund may purchase or sell financial
      futures contracts and options on such financial futures contracts.
      Financial 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.

Notes to Financial Statements (continued)

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.

o     Swaps -- The Fund may enter into swap agreements, which are OTC contracts
      in which the Fund and a counterparty agree to make periodic net payments
      on a specified notional amount. The net payments can be made for a set
      period of time or may be triggered by a predetermined credit event. The
      net periodic payments may be based on a fixed or variable interest rate;
      the change in market value of a specified security, basket of securities,
      or index; or the return generated by a security. These periodic payments
      received or made by the Fund are recorded in the accompanying Statement of
      Operations as realized gains or losses, respectively. Gains or losses are
      also realized upon termination of the swap agreements. Swaps are
      marked-to-market daily and changes in value are recorded as unrealized
      appreciation (depreciation). Risks include changes in the returns of the
      underlying instruments, failure of the counterparties to perform under the
      contracts' terms and the possible lack of liquidity with respect to the
      swap agreements.

(c) Municipal bonds held in trust -- The Fund invests in leveraged residual
certificates ("TOB Residuals") issued by tender option bond trusts ("TOBs"). A
TOB is established by a third party sponsor forming a special purpose entity,
into which the Fund, or an agent on behalf of the Fund, transfers municipal
securities. A TOB typically issues two classes of beneficial interests:
short-term floating rate certificates, which are sold to third party investors,
and residual certificates, which are generally issued to the Fund which made the
transfer or to affiliates of the Fund. The transfer of the municipal securities
to a TOB does not qualify for sale treatment under Statement of Financial
Accounting Standards No. 140 "Accounting for Transfers and Servicing of
Financial Assets and Extinguishments of Liabilities," therefore the municipal
securities deposited into a TOB are presented in the Fund's schedule of
investments and the proceeds from the transaction are reported as a liability
for trust certificates of the Fund. Similarly, proceeds from residual
certificates issued to affiliates, if any, from the transaction are included in
the liability for trust certificates. Interest income from the underlying
security is recorded by the Fund on an accrual basis. Interest expense incurred
on the secured borrowing and other expenses related to remarketing,
administration and trustee services to a TOB are reported as expenses of the
Fund. The floating rate certificates have interest rates that generally reset
weekly and their holders have the option to tender certificates to the TOB for
redemption at par at each reset date. The residual interests held by the Fund
include the right of the Fund (1) to cause the holders of a proportional share
of the floating rate certificates to tender their certificates at par, and (2)
to transfer a corresponding share of the municipal securities from the TOB to
the Fund. At July 31, 2007, the aggregate value of the underlying municipal
securities transferred to TOBs was $119,443,408, the related liability for trust
certificates was $57,132,500 and the range of interest rates on the liability
for trust certificates was 5% to 6%.

Financial transactions executed through TOBs generally will underperform the
market for fixed rate municipal bonds in a rising interest rate environment, but
tend to outperform the market for fixed rate bonds when interest rates decline
or remain relatively stable. Should short-term interest rates rise, the Fund's
investment in TOB Residuals likely will adversely affect the Fund's investment
income -- net and distributions to shareholders. Fluctuations in the market
value of municipal securities deposited into the TOB may adversely affect the
Fund's net asset value per share.

While the Fund's investment policies and restrictions expressly permit
investments in inverse floating rate securities such as TOB Residuals, they
generally do not allow the Fund to borrow money for purposes of making
investments. The Fund's management believes that the Fund's restrictions on
borrowings do not apply to the secured borrowings deemed to have occurred for
accounting purposes.

(d) 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.

(e) 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.

Notes to Financial Statements (continued)

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

(g) Recent accounting pronouncement -- In July 2006, the Financial Accounting
Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting
for Uncertainty in Income Taxes -- an interpretation of FASB Statement No. 109."
FIN 48 prescribes the minimum recognition threshold a tax position must meet in
connection with accounting for uncertainties in income tax positions taken or
expected to be taken by an entity, including mutual funds, before being measured
and recognized in the financial statements. Management has evaluated the
application of FIN 48 to the Fund, and has determined that the adoption of FIN
48 does not have a material impact on the Fund's financial statements. The Fund
files U.S. and various state tax returns. No income tax returns are currently
under examination. The statute of limitations on the Fund's tax returns remains
open for the years ended December 31, 2003 through December 31, 2006.

In September 2006, Statement of Financial Accounting Standards No. 157, "Fair
Value Measurements" ("FAS 157"), was issued and is effective for fiscal years
beginning after November 15, 2007. FAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. At this time, management is evaluating the implications of FAS 157
and its impact on the Fund's financial statements, if any, has not been
determined.

In addition, in February 2007, Statement of Financial Accounting Standards No.
159, "The Fair Value Option for Financial Assets and Financial Liabilities"
("FAS 159"), was issued and is effective for fiscal years beginning after
November 15, 2007. Early adoption is permitted as of the beginning of a fiscal
year that begins on or before November 15, 2007, provided the entity also elects
to apply the provisions of FAS 157. FAS 159 permits entities to choose to
measure many financial instruments and certain other items at fair value that
are not currently required to be measured at fair value. FAS 159 also
establishes presentation and disclosure requirements designed to facilitate
comparisons between entities that choose different measurement attributes for
similar types of assets and liabilities. At this time, management is evaluating
the implications of FAS 159 and its impact on the Fund's financial statements,
if any, has not been determined.

2. Investment Advisory Agreement and Transactions with Affiliates:

The Fund has entered into an Investment Advisory Agreement with BlackRock
Advisors, LLC (the "Manager"), an indirect, wholly owned subsidiary of
BlackRock, Inc. Merrill Lynch & Co., Inc. ("Merrill Lynch") and The PNC

BlackRock 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 BlackRock 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.

to vote proxies relating to portfolio securities is available (1) without
