Semi-Annual Report

MuniYield
Florida Fund


www.mlim.ml.com


MuniYield Florida Fund seeks to provide shareholders with as high a
level of current income exempt from Federal income taxes as is
consistent with its investment policies and prudent investment
management by investing primarily in a portfolio of long-term
municipal obligations the interest on which, in the opinion of bond
counsel to the issuer, is exempt from Federal income taxes and which
enables shares of the Fund to be exempt from Florida intangible
personal property taxes.

This report, including the financial information herein, is
transmitted to shareholders of MuniYield Florida Fund 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 Shares and intends to
remain leveraged by issuing Preferred Shares to provide the Common
Shareholders with a potentially higher rate of return. Leverage
creates risks for Common Shareholders, including the likelihood of
greater volatility of net asset value and market price of shares of
the Common Shares, and the risk that fluctuations in the short-term
dividend rates of the Preferred Shares may affect the yield to
Common Shareholders. Statements and other information herein are as
dated and are subject to change.

MUNIYIELD FLORIDA FUND


The Benefits
And Risks of
Leveraging


MuniYield Florida Fund utilizes leveraging to seek to enhance the
yield and net asset value of its Common Shares. However, these
objectives cannot be achieved in all interest rate environments. To
leverage, the Fund issues Preferred Shares, which pay dividends at
prevailing short-term interest rates, and invests the proceeds in
long-term municipal bonds. The interest earned on these investments
is paid to Common 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 Shares. However, in order to
benefit Common 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 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 Share
capitalization of $100 million and the issuance of Preferred
Shares 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 Shares 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 Shares.

In this case, the dividends paid to Preferred Shareholders are
significantly lower than the income earned on the fund's long-term
investments, and therefore the Common 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 Shares will be reduced or eliminated completely. At the same
time, the market value of the fund's Common Shares (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
Shares' net asset value will reflect the full decline in the price
of the portfolio's investments, since the value of the fund's
Preferred Shares does not fluctuate. In addition to the decline in
net asset value, the market value of the fund's Common Shares 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 of 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 such securities.



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.



MuniYield Florida Fund, April 30, 2003


DEAR SHAREHOLDER


For the six months ended April 30, 2003, the Common Shares of
MuniYield Florida Fund had a net annualized yield of 6.02%, based on
a period-end per share net asset value of $15.33 and $.458 per share
income dividends. Over the same period, the total investment return
on the Fund's Common Shares was +5.79%, based on a change in per
share net asset value from $14.97 to $15.33, and assuming
reinvestment of $.456 per share ordinary income dividends.

For the six-month period ended April 30, 2003, the Fund's Auction
Market Preferred Shares had an average yield of 1.11% for Series A
and 1.03% for Series B.

For a description of the Fund's total investment return based on a
change in the per share market value (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 the Financial Statements included in 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
Fund's market value can vary significantly from total investment
return based on changes in the Fund's net asset value.


The Municipal Market Environment
During the six-month period ended April 30, 2003, amid considerable
weekly and monthly volatility, long-term fixed income interest rates
generally declined. Geopolitical tensions and volatile equity
valuations continued to overshadow economic fundamentals as they
have for most of the last 12 months. Reacting to the strong U.S.
equity rally that began last October, fixed income bond yields
remained under pressure in November 2002, as U.S. equity markets
continued to strengthen. During November, the Standard & Poor's 500
(S&P 500) Index rose an additional 5.50%. Equity prices were
supported by further signs of U.S. economic recovery, especially
improving labor market activity. In late November, third-quarter
2002 U.S. gross domestic product growth was 4%, well above the
second-quarter 2002 rate of 1.30%. Financial conditions were also
strengthened by a larger-than-expected reduction in short-term
interest rates by the Federal Reserve Board in early November. The
Federal Funds target rate was lowered 50 basis points (0.50%) to
1.25%, its lowest level since the 1960s. This action by the Federal
Reserve Board was largely viewed as being taken to bolster the
sputtering U.S. economic recovery. Rebounding U.S. equity markets
and the prospects for a more substantial U.S. economic recovery
pushed long-term U.S. Treasury yield levels to 5.10% by late
November.

However, into early 2003, softer equity prices and renewed investor
concerns about U.S. military action against Iraq and North Korea
again pushed bond prices higher. Reacting to disappointing holiday
sales and corporate managements' attempts to scale back analysts'
expectation of future earnings, the S&P 500 Index declined more than
10% from December 2002 to February 2003. Fearing an eventual
U.S./Iraq military confrontation in 2003, investors again sought the
safety of U.S. Treasury obligations and the prices of fixed income
issues rose. By the end of February 2003, U.S. Treasury bond yields
had declined approximately 40 basis points to 4.67%.

Bond yields continued to fall into early March. Once direct U.S.
military action against Iraq began, bond yields quickly rose. Prior
uncertainty surrounding the Iraqi situation was obviously removed
and early U.S. military successes fostered the hope that the
conflict would be quickly and positively concluded. Concurrently,
the S&P 400 Index rose over 6% as investors, in part, sold fixed
income issues to purchase equities in anticipation of a strong
U.S. economic recovery once the Iraqi conflict was resolved. By
mid-March, U.S. Treasury bond yields again rose to above 5%.
However, as there was growing sentiment that hostilities may not be
resolved in a matter of weeks, U.S. Treasury bond yields again
declined to end the month at 4.81%.

For the six months ended April 30, 2003, long-term U.S. Treasury
bond yields ratcheted back to near 5% by mid-April, as U.S. equity
markets continued to improve and the safe-haven premium U.S.
Treasury issues had commanded prior to the beginning of the Iraqi
conflict continued to be withdrawn. However, with the quick positive
resolution of the Iraqi war, investors quickly resumed their focus
on the fragile U.S. economic recovery. Business activity in the
United States has remained sluggish, especially job creation.
Investors have also been concerned that the recent SARS outbreak
would have a material, negative impact on world economic conditions,
especially in China and Japan. First quarter 2003 U.S. gross
domestic product was released in late April initially estimating
U.S. economic activity to be growing at 1.60%, well below many
analysts' assessments. These factors, as well as the possibility
that the Federal Reserve Board could again lower short-term interest
rates to encourage more robust U.S. economic growth, pushed bond
prices higher during the last two weeks of the period. By April 30,
2003, long-term U.S. Treasury bond yields had declined to almost
4.75%. Over the past six months, long-term U.S. bond yields fell
more than 20 basis points.

For the six months ended April 30, 2003, long-term tax-exempt bond
yields also fell modestly. Yield volatility was reduced relative to
that seen in U.S. Treasury issues, as municipal bond prices were
much less sensitive to worldwide geopolitical pressures on a daily
and weekly basis. Tax-exempt bond yields generally followed their
taxable counterparts higher, responding to a more positive U.S.
fixed income environment and continued slow economic growth. After
rising approximately 10 basis points in November 2002 to 5.30%,
municipal bond yields generally declined through February 2003. At
February 28, 2003, long-term tax-exempt revenue bond yields, as
measured by the Bond Buyer Revenue Bond Index, fell to approximately
5.05%. However, similar to U.S. Treasury bond yields, once military
action began in Iraq, municipal bond yields rose sharply to nearly
5.20% before declining to approximately 5.10% by the end of April.
Over the past six months, long-term tax-exempt bond yields fell
approximately 11 basis points, slightly less than U.S. Treasury
obligations.

A number of factors have combined to generate consistently strong
demand for municipal bonds throughout the six-month period ended
April 30, 2003. Generally weak U.S. equity markets have supported
continued positive demand for tax-exempt products as investors have
sought the relative security of fixed income issues. Also, with tax-
exempt money market rates near 1%, the demand for longer maturity
municipal issues has increased as investors have opted to buy longer
maturity issues rather than remain in cash reserves. Additionally,
investors received approximately $30 billion in January 2003 from
bond maturities, coupon income and proceeds from early redemptions.
However, these positive demand factors were not totally able to
offset the increase in tax-exempt new-issue supply, preventing more
significant declines in tax-exempt bond yields. This modest
underperformance has served to make municipal bonds a particularly
attractive purchase relative to their taxable counterparts.
Throughout most of the yield curve, municipal bonds have been able
to be purchased at yields near or exceeding those of comparable
Treasury issues. Compared to their recent historical averages of
82% - 88% of U.S. Treasury yields, municipal bond yield ratios in
their current 95% - 105% range are likely to prove attractive to
long-term investors.

Declining U.S. equity markets and escalating geopolitical pressures
have resulted in reduced economic activity and consumer confidence.
It is important to note that, despite all the recent negative
factors impeding the growth of U.S. businesses, the U.S. economy
still grew at an approximate 2.50% rate for all of 2002, twice that
of 2001. Similar expansion is expected for early 2003. Lower oil
prices, reduced geopolitical uncertainties, increased Federal
spending for defense, and a likely Federal tax cut are all factors
which should promote stronger economic growth later this year.
However, it is questionable to expect that business and investor
confidence can be so quickly restored as to trigger dramatic,
explosive U.S. economic growth and engender associated, large-scale
interest rate increases. The resumption of solid economic growth is
likely to be a gradual process accompanied by equally graduated
increases in bond yields. Moderate economic growth, especially
within a context of negligible inflationary pressures, should not
greatly endanger the positive fixed income environments tax-exempt
products currently enjoy.



MuniYield Florida Fund, April 30, 2003


Specific to Florida, the state's general fund budget proposal for
fiscal year 2003 - 2004 came in at $53.9 billion, a 7.0% increase
from the prior year. This budget will attempt to close a $2 billion
fiscal year 2004 operating shortfall. It includes currently passed
referendums for smaller classroom sizes, enrolling four-year olds
as pre-kindergartners and a high-speed rail line. Florida is
projected to end fiscal year 2002 - 2003 with an operating surplus
of $140 million and a rainy day fund at $960 million, a sharp
contrast to most other states. With the implementation of the
constitutional amendments, spending will increase faster than
revenues and will force the state to borrow. In fiscal year 2004,
$3 billion is earmarked for schools. However, this is just
scratching the surface of an estimated $4 billion - $27 billion
price tag for education during the next eight years. With this
increase in spending in the current fiscal year, other programs
will be reduced and/or eliminated. Some proposed cuts include
$200 million from transportation, $111 million from universities,
and $51 million from juvenile crime prevention. Additional
expenditure savings will be derived by outsourcing state agency
functions such as payroll and benefits administration totaling
another $200 million. These reductions, along with an increase in
the corporate tax structure, the inclusion of video lottery
terminals being placed in dog and horse racetracks and improving
sales tax collections are estimated to generate more than
$1 billion. Proposed expenditure reductions, revenue increases,
along with a sizable rainy day fund, will enable the state to
operate without increasing other taxes. However, the state balanced
its budget by burdening local governments and universities by asking
the voters to increase local sales taxes and/or increase tuition to
meet local operations. Even though the state is being pressured by a
weak national economy, we believe Florida is in a position during
the upcoming year to perform well given its prospective management
and financial flexibility.


Portfolio Strategy
During the six-month period ended April 30, 2003, we maintained our
neutral position on the municipal bond market. We continued to focus
on reducing the volatility of the Fund by selling some of the Fund's
10-year - 15-year bonds and purchasing larger-couponed bonds
maturing in 20 years - 30 years. We believe these longer maturities
are likely to enhance the Fund's income stream and help preserve
asset valuations in future periods of market volatility. During the
six-month period, Florida's new-issue supply was up approximately
50% compared to the same time a year ago. Despite the heavy supply,
retail and institutional demand remained quite strong. However, this
strong demand hindered us from fully implementing our desired
strategy. The vast majority of new bond issuance has been structured
as par bonds, which are more price sensitive and produce less income
than premium coupon structured issues. Going forward, the municipal
bond curve is expected to remain quite steep. We will maintain our
neutral position and remain fully invested in an effort to enhance
shareholder income.

During the six-month period ended April 30, 2003, the Fund's
borrowing costs remained in the 1% - 1.50% range, with interest
rates presently near 1%. These very attractive funding levels, in
combination with the steep tax-exempt yield curve, have continued to
generate significant income benefits to the Fund's Common
Shareholder. We do not expect any material reduction in our
borrowing costs in 2003 as no additional monetary easings by the
Federal Reserve Board are anticipated. We expect our short-term
borrowing costs to remain at current attractive levels for most of
the coming year. However, should the spread between short-term and
long-term interest rates narrow, the benefits of leverage will
decline and the yield to the Fund's Common Shareholders will be
reduced. (For a more complete explanation of the benefits and risks
of leveraging, see page 1 of this report to shareholders.)


In Conclusion
We appreciate your continuing interest in MuniYield Florida Fund,
and we look forward to serving your investment needs in the months
and years to come.

MuniYield Florida Fund, April 30, 2003


NOTES TO FINANCIAL STATEMENTS


1. Significant Accounting Policies:
MuniYield Florida Fund (the "Fund") is registered under the
Investment Company Act of 1940 as a non-diversified, closed-end
management investment company. The Fund's financial statements are
prepared in conformity with accounting principles generally accepted
in the United States of America, which may require the use of
management accruals and estimates. These unaudited financial
statements reflect all adjustments, which are, in the opinion of
management, necessary to a fair statement of the results for the
interim period presented. All such adjustments are of a normal,
recurring nature. The Fund determines and makes available for
publication the net asset value of its Common Shares on a weekly
basis. The Fund's Common Shares are listed on the New York Stock
Exchange under the symbol MYF. 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 most recent
bid price or yield equivalent as obtained by the Fund's pricing
service from dealers that make markets in such 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). Securities with remaining maturities 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 their fair value as determined in good faith
by or under the direction of the Board of Trustees 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 Trustees.

(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
movement 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.

* 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.

* Options--The Fund is authorized to write covered call options and
purchase 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 to reflect 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.

* Forward interest rate swaps--The Fund is authorized to enter into
forward interest rate swaps. In a forward interest rate swap, the
Fund and the counterparty agree to pay or receive interest on a
specified notional contract amount, commencing on a specified future
effective date, unless terminated earlier. The value of the
agreement is determined by quoted fair values received daily by the
Fund from the counterparty. When the agreement is closed, the Fund
records a realized gain or loss in an amount equal to the value of
the agreement.

(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. Divided
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 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

For the six months ended April 30, 2003, the Fund reimbursed FAM

depreciated securities. The aggregate cost of investments at
April 30, 2003 for Federal income tax purposes was $281,745,764.


4. Share Transactions:
The Fund is authorized to issue an unlimited number of shares of
beneficial interest, including Preferred Shares, par value $.10 per
share, all of which were initially classified as Common Shares. The
Board of Trustees is authorized, however, to reclassify any unissued
shares of beneficial interest without approval of the holders of
Common Shares.

Common Shares

2003 and for the year ended October 31, 2002 remained constant.

Preferred Shares
Auction Market Preferred Shares ("AMPS") are Preferred Shares of the
Fund, with a par value of $.10 per share and a liquidation
preference of $25,000 per share plus accrued and unpaid dividends,
that entitle their holders to receive cash dividends at an annual
rate that may vary for the successive dividend periods. The yields
in effect at April 30, 2003 were as follows: Series A, 1.20% and
Series B, 1.15%.

Shares issued and outstanding during the six months ended April 30,
2003 and for the year ended October 31, 2002 remained constant.

The Fund pays commissions to certain broker-dealers at the end of
each auction at an annual rate ranging from .25% to .375%,
calculated on the proceeds of each auction. For the six months ended

net investment income to its shareholders on a monthly basis. In
order to provide shareholders with a more consistent yield to the
current trading price of shares of Common Stock of the Fund, 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 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.
