A Letter From the President

Dear Shareholder

Now more than half behind us, 2003 has been a meaningful year in many respects.
Perhaps the most significant development was the conclusion of all-out war in
Iraq. Although not especially sensitive to geopolitical events, the municipal
market has not been exempt from the general market excitement we have seen since
fighting gave way to restructuring in Iraq.

Municipal bond yields rose and fell in response to war fears, equity market
uncertainty, sub par economic growth, unemployment and deflation. By the end of
July, long-term municipal revenue bond yields stood at 5.4%, as measured by the
Bond Buyer Revenue Bond Index. With many state deficits at record levels,
municipalities issued more than $200 billion in new long-term tax-exempt bonds
during the six-month period ended July 31, 2003, an increase of more than 20%
versus the same six months of 2002. The availability of bonds, together with
attractive yield ratios relative to U.S. Treasury issues, made municipal bonds a
popular fixed income investment alternative.

Against this backdrop, our portfolio managers continued to work diligently to
deliver on our commitment to provide superior performance within reasonable
expectations for risk and return. This included striving to outperform our peers
and the market indexes. With that said, remember also that the advice and
guidance of a skilled financial advisor can mean the difference between fruitful
and fruitless investing. A financial professional can help you choose those
investments that will best serve you as you plan for your financial future.

Finally, I am proud to premiere a new look to our shareholder communications.
Our portfolio manager commentaries have been trimmed and organized in such a way
that you can get the information you need at a glance, in plain language.
Today's markets are confusing enough. We want to help you put it all in
perspective. The report's new size also allows us certain mailing efficiencies.
The cost savings in both production and postage are passed on to the fund and,
ultimately, to fund shareholders.

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

A Discussion With Your Fund's Portfolio Manager

      We have been working to manage volatility and to take advantage of the
steep municipal yield curve, selling bonds maturing in 10 - 15 years and
purchasing larger-coupon bonds maturing in 20 - 30 years.

Discuss the recent market environment relative to municipal bonds.

Amid considerable interest rate volatility, U.S. Treasury bond yields were
higher at 5.35% at the end of July, 2003 than they had been six months earlier.
Volatile equity markets, concerns over the Iraqi conflict, and sub par economic
growth combined to generally push interest rates lower through June. Bond
yields, however, moved sharply higher in July in response to more positive
business activity, especially continued strong homes sales and improving
employment trends.

Long-term tax-exempt bond yields also rose over the six months ended July 31,
2003, although to a lesser extent than U.S. Treasury obligations. Yield
volatility was lower than that seen in U.S. Treasury issues, as municipal bond
prices typically are less sensitive to worldwide geopolitical pressures on a
daily and weekly basis. By the end of July, long-term municipal revenue bond
yields, as measured by the Bond Buyer Revenue Bond Index, stood at 5.4%.

The municipal market outperformed the U.S. Treasury market over the past six
months, despite a dramatic increase in new bond issuance. Recent semi-annual
issuance has, in fact, exceeded the annual issuance seen during much of the
mid-1990s. The monthly issuance for July 2003, at almost $30 billion,
represented the largest amount of tax-exempt bonds ever sold in the month of
July. Historically low interest rates over the past year have been used by state
and local governments as an opportunity to finance existing infrastructure needs
and refinance outstanding, higher-coupon issues. Current estimates for 2003
municipal bond new issuance are approximately $350 billion, similar to 2002's
record high issuance.

A number of factors continue to foster strong investor demand for municipal
bonds. Tax-exempt money market rates have remained below 1% for much of this
year, forcing investors to invest in longer maturities to generate desired
levels of coupon income. In July and August 2003, investors are expected to
receive approximately $60 billion in coupon income, bond maturities and the
proceeds from early redemptions. We believe much of these proceeds are likely to
be reinvested in the municipal market.

As an asset class, municipal bonds have remained an attractive investment
alternative, especially relative to U.S. Treasury issues. At the end of July
2003, tax-exempt bond yields were 85% - 93% of comparable U.S. Treasury issues,
well in excess of their historic average of 82% - 88%. Current yield ratios have
made municipal securities attractive to both retail and institutional investors.
We expect the tax-exempt market's favorable technical position to remain stable
in the near term, therefore, an increase in bond issuance during the remainder
of 2003 is not likely to significantly impact the municipal bond market's
performance.

While many investors are concerned about how economic growth might affect bond
prices and yield, we believe moderate economic growth, especially within a
context of negligible inflationary pressures, should not greatly endanger the
positive fixed income environments tax-exempt products have enjoyed.

How did conditions in the state of Florida affect the Fund during the period?

Conditions have been relatively favorable. The state of Florida maintains solid
credit ratings of Aa2, AA+ and AA, with a stable trend, from Moody's, Standard &
Poor's and Fitch, respectively. Florida continues to attract new residents
because of its climate, low cost of living and continued job growth. These
factors, along with a proactive state government, allow for greater flexibility
in responding to economic downturns than many other states. Having said that,
ongoing population increases have put some strain on the state's social services
programs, especially education, health care and mass transit. While most state
revenues have been below projections because of a sluggish domestic economy,
Florida General Fund revenues are projected to be up by 1.6% in fiscal year 2003
and 2.6% in fiscal year 2004. The state has enacted sizable budget cuts
consisting of a hiring freeze, a rollback of tax breaks and other expenditure
reductions. These actions, in our opinion, affirm the state's conservative
fiscal nature.


4       MERRILL LYNCH FLORIDA MUNICIPAL BOND FUND       JULY 31, 2003



Despite generally weak economic conditions, the state has maintained a Budget
Stabilization Fund of $959 million for fiscal year 2003. However, Governor Jeb
Bush is facing considerable financial pressure from recently enacted
voter-approved measures for increased spending on education and a high-speed
rail system. Because the cost could total up to $27 billion, the governor is
expected to attempt to repeal these measures. The state's fiscal year 2004
budget was recently passed by shifting increased costs to local governments. In
order to finance these additional costs, local municipalities will have to
increase property taxes or local sales taxes through voter initiatives. As a
result, the Fund's strategy has been to purchase insured general obligation
bonds and their equivalents to avoid price volatility associated with any
reduction in credit quality due to increased spending and/or borrowing.

How did the Fund perform during the fiscal year?

For the 12-month period ended July 31, 2003, the Fund's Class A, Class B, Class
C and Class I Shares had total returns of +3.66%, +3.35%, +3.24% and +3.87%,
respectively, performing in line with the +3.60% return of the unmanaged
benchmark Lehman Brothers Municipal Bond Index and outperforming its Lipper peer
group of Florida Municipal Debt Funds, which had an average return of +2.89% for
the same period. (Fund results shown do not reflect sales charges and would be
lower if sales charges were included. Complete performance information can be
found on pages 6 - 8 of this report to shareholders.)

During the fiscal period, we maintained our neutral position toward the
municipal bond market and aimed to reduce the Fund's volatility. Taking
advantage of a very steep tax-exempt yield curve, we began to sell bonds
maturing in 10 years - 15 years, and purchased larger-coupon bonds maturing in
20 years - 30 years. This strategy worked well in recent months as the
intermediate sector of the Florida municipal market experienced considerable
volatility.

What changes were made to the portfolio during the period?

During the fiscal year, we made no significant changes to the portfolio or our
investment strategy. We continued to sell bonds in the 10-year - 15-year
maturity range. With the proceeds, we purchased premium-coupon bonds in the
20-year - 30-year maturity range, whenever they became available in the market.

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

We believe the municipal market will continue to be volatile over the next few
months. We intend to maintain our neutral posture. As long as the municipal
curve remains steep, we will continue to sell the intermediate part of the curve
and, with the proceeds, purchase premium coupon bonds in the 20-year - 30-year
maturity range. We expect that the Fund will remain fully invested in order to
seek to provide a high level of tax-exempt income to its shareholders.

Effective April 14, 2003, the share class names for the Merrill Lynch family of
mutual funds were changed to be consistent with the standard share classes of
most other mutual fund families. As of that date, all Class A Shares were
redesignated Class I Shares. At the same time, Class D Shares were redesignated
Class A Shares. There are no changes to the Class B or Class C share class
labels. Trading symbols have not changed nor have current eligibility rules or
pricing structures. This redesignation of share classes does not impact your
investment in any way.

About Fund Performance

Effective April 14, 2003, Class A Shares were redesignated Class I Shares and
Class D Shares were redesignated Class A Shares. Investors are able to purchase
shares of the Fund through multiple pricing alternatives:

o     Class A Shares incur a maximum initial sales charge of 4% and an account
      maintenance fee of 0.10% (but no distribution fee).

o     Effective December 1, 2002, Class B Shares are subject to a maximum
      contingent deferred sales charge of 4%, declining to 0% after six years.
      All Class B Shares purchased prior to December 1, 2002 will maintain the
      four-year schedule. In addition, Class B Shares are subject to a
      distribution fee of 0.25% and an account maintenance fee of 0.25%. These
      shares automatically convert to Class A Shares after approximately ten
      years. (There is no initial sales charge for automatic share conversions.)

o     Class C Shares are subject to a distribution fee of 0.35% and an account
      maintenance fee of 0.25%. In addition, Class C Shares are subject to a 1%
      contingent deferred sales charge if redeemed within one year of purchase.

o     Class I Shares incur a maximum initial sales charge (front-end load) of 4%
      and bear no ongoing distribution or account maintenance fees. Class I
      Shares are available only to eligible investors.

None of the past results shown should be considered a representation of future
performance. Performance results do not reflect the deduction of taxes that a
shareholder would pay on fund distributions or the redemption of fund shares.
Figures shown in each of the following tables assume reinvestment of all
dividends and capital gains distributions at net asset value on the payable
date. Investment return and principal value of shares will fluctuate so that
shares, when redeemed, may be worth more or less than their original cost.
Dividends paid to each class of shares will vary because of the different levels
of account maintenance, distribution and transfer agency fees applicable to each
class, which are deducted from the income available to be paid to shareholders.

Notes to Financial Statements

1. Significant Accounting Policies:

Merrill Lynch Florida Municipal Bond Fund (the "Fund") is part of Merrill Lynch
Multi-State Municipal Series Trust (the "Trust"). The Fund is registered under
the Investment Company Act of 1940, as amended, as a non-diversified, open-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. The
Fund offers multiple classes of shares. Effective April 14, 2003, Class A Shares
were redesignated Class I Shares and Class D Shares were redesignated Class A
Shares. The Fund's financial statements and financial highlights contained
within this report reflect the new share class redesignation. Shares of Class A
and Class I are sold with a front-end sales charge. Shares of Class B and Class
C may be subject to a contingent deferred sales charge. All classes of shares
have identical voting, dividend, liquidation and other rights and the same terms
and conditions, except that Class A, Class B and Class C Shares bear certain
expenses related to the account maintenance of such shares, and Class B and
Class C Shares also bear certain expenses related to the distribution of such
shares. Each class has exclusive voting rights with respect to matters relating
to its account maintenance and distribution expenditures. Income, expenses
(other than expenses attributable to a specific class) and realized and
unrealized gains and losses on investments are allocated daily to each class
based on its related net assets. The following is a summary of significant
accounting policies followed by the Fund.

(a) Valuation of investments -- Municipal bonds and other portfolio securities
in which the Fund invests are traded primarily in the over-the-counter municipal
bond and money 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 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 settlement prices as of the close of such exchanges. Short-term
investments 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 fair value as
determined in good faith by or under the direction of the Board of Trustees of
the Trust, including valuations furnished by a pricing service retained by the
Trust, which may utilize a matrix system for valuations. The procedures of the
pricing service and its valuations are reviewed by the officers of the Trust
under the general supervision of the 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.

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.

Notes to Financial Statements (continued)

(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.

(f) Expenses -- Certain expenses have been allocated to the individual Funds in
the Trust on a pro rata basis based upon the respective aggregate net asset
value of each Fund included in the Trust.

(g) Reclassification -- Accounting principles generally accepted in the United
States of America require that certain components of net assets be adjusted to
reflect permanent differences between financial and tax reporting. Accordingly,
the current year's permanent book/tax difference of $6,469,079 has been
reclassified between paid-in capital in excess of par and accumulated realized
capital losses. This reclassification has no effect on net assets or net asset
value per share.

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. The Fund has also entered into a
Distribution Agreement and Distribution Plans with FAM Distributors, Inc.
("FAMD" or the "Distributor"), which is a wholly-owned subsidiary of Merrill
Lynch Group, Inc.

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
based upon the average daily value of the Fund's net assets at the following
annual rates: .55% of the Fund's average daily net assets not exceeding $500
million; .525% of average daily net assets in excess of $500 million but not
exceeding $1 billion; and .50% of average daily net assets in excess of $1
billion. For the year ended July 31, 2003, FAM reimbursed the Fund in the amount
of $4,951.

Pursuant to the Distribution Plans adopted by the Fund in accordance with Rule
12b-1 under the Investment Company Act of 1940, the Fund pays the Distributor
ongoing account maintenance and distribution fees. The fees are accrued daily
and paid monthly at annual rates based upon the average daily net assets of the
shares as follows:

- -------------------------------------------------------------------------------
                                                   Account         Distribution
                                               Maintenance Fee          Fee
- -------------------------------------------------------------------------------
Class A .................................            .10%               --
Class B .................................            .25%              .25%
Class C .................................            .25%              .35%
- -------------------------------------------------------------------------------

Pursuant to a sub-agreement with the Distributor, Merrill Lynch, Pierce, Fenner
& Smith Incorporated ("MLPF&S"), a subsidiary of ML & Co., also provides account
maintenance and distribution services to the Fund. The ongoing account
maintenance fee compensates the Distributor and MLPF&S for providing account
maintenance services to Class A, Class B and Class C shareholders. The ongoing
distribution fee compensates the Distributor and MLPF&S for providing
shareholder and distribution-related services to Class B and Class C
shareholders.

5. Short-Term Borrowings:

The Fund, along with certain other funds managed by FAM and its affiliates, is a
party to a $500,000,000 credit agreement with Bank One, N.A. and certain other
lenders. The Fund may borrow under the credit agreement to fund shareholder
redemptions and for other lawful purposes other than for leverage. The Fund may
borrow up to the maximum amount allowable under the Fund's current prospectus
and statement of additional information, subject to various other legal,
regulatory or contractual limits. The Fund pays a commitment fee of .09% per
annum based on the Fund's pro rata share of the unused portion of the credit
agreement. Amounts borrowed under the credit agreement bear interest at a rate
equal to, at each fund's election, the Federal Funds rate plus .50% or a base
rate as determined by Bank One, N.A. On November 29, 2002, the credit agreement
was renewed for one year under the same terms, except that the commitment was
reduced from $1,000,000,000 to $500,000,000. The Fund did not borrow under the
credit agreement during the year ended July 31, 2003.

The tax character of distributions paid during the fiscal years ended July 31,
2003 and July 31, 2002 was as follows:

- -------------------------------------------------------------------------------
                                                  7/31/2003          7/31/2002
- -------------------------------------------------------------------------------
Distributions paid from:
  Tax-exempt income ......................      $  7,823,358       $  7,672,844
                                                -------------------------------
Total distributions ......................      $  7,823,358       $  7,672,844
                                                ===============================

As of July 31, 2003, the components of accumulated losses on a tax basis were as
follows:

- -----------------------------------------------------------------------------
Undistributed tax-exempt income--net ....................         $    85,510
Undistributed long term capital gain--net ...............                  --
                                                                  -----------
Total undistributed earnings--net .......................              85,510
Capital loss carryforward ...............................          (7,525,890)*
Unrealized gains--net ...................................           2,040,513**
                                                                  -----------
Total accumulated losses--net ...........................         $(5,399,867)
                                                                  ===========

*     On July 31, 2003, the Fund had a net capital loss carryforward of
      $7,525,890, of which $2,275,703 expires in 2004; $4,131,859 expires in
      2008 and $1,118,328 expires in 2009. This amount will be available to
      offset like amounts of any future taxable gains.

**    The difference between book-basis and tax-basis net unrealized gains is
      attributable primarily to the tax deferral of losses on wash sales, the
      tax deferral of losses on straddles, and the difference between book and
      tax amortization methods for premiums and discounts on fixed income
      securities.

Independent Auditors' Report

To the Shareholders and Board of Trustees of
Merrill Lynch Florida Municipal Bond Fund of
Merrill Lynch Multi-State Municipal Series Trust:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Merrill Lynch Florida Municipal Bond Fund of
Merrill Lynch Multi-State Municipal Series Trust as of July 31, 2003, and the
related statement of operations for the year then ended, the statements of
changes in net assets for each of the two years in the period then ended, and
the financial highlights for each of the five years in the period then ended.
These financial statements and financial highlights are the responsibility of
the Fund's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of July 31, 2003 by correspondence with the custodian and
brokers; where replies were not received from brokers, we performed other
auditing procedures. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Merrill Lynch Florida Municipal Bond Fund of Merrill Lynch Multi-State Municipal
Series Trust as of July 31, 2003, the results of its operations for the year
then ended, the changes in its net assets for each of the two years in the
period then ended, and its financial highlights for each of the five years in
the period then ended, in conformity with accounting principles generally
accepted in the United States of America.
