TO OUR SHAREHOLDERS:
- --------------------------------------------------------------------------------

For the year ended March 31, 2003, CMA Connecticut Municipal Money Fund paid
shareholders a net annualized yield of .70%.* As of March 31, 2003, the Fund's
7-day yield was .51%.

Economic Environment

During the six-month period ended March 31, 2003, equity and fixed income
markets and the domestic economy continued to be influenced strongly by
developments outside of the financial sector. The uncertainty that surrounded
the effectiveness of the weapons inspections by the United Nations and the
eventual onset of war with Iraq in mid-March weighed heavily on consumer and
corporate spending. Despite the increased volatility in the equity markets
because of geopolitical uncertainty, the Dow Jones Industrial Average and the
NASDAQ Composite Index were able to post positive gains for the period. However,
by March 31, 2003 both indexes were well off the highs reached in late November
2002.

Fixed income investors favored the very short end of the U.S. Treasury yield
curve because of its relative safety. Six-month and two-year U.S. Treasury bills
experienced solid gains that lowered yields on these instruments 43 basis points
(.43%) and 31 basis points, respectively. Finally, the Federal Open Market
Committee has met four times since September 30, 2002, lowering interest rates
50 basis points at its meeting on November 6, 2002 and bringing the Federal
Funds borrowing rate to a historic low of 1.25%. Interestingly, at the Federal
Open Market Committee meeting on March 18, 2003, the Federal Reserve Board chose
not to issue its customary stated bias, which typically characterizes the
committee's current risk assessment for the economy. This may have left the door
open for the Federal Reserve Board to cut the Federal Funds rate between
meetings should conditions warrant.

Specific to Connecticut, the state is facing a growing budget deficit as tax
revenues continue to fall well short of projected levels. The projected deficit
for fiscal year 2003 may exceed $500 million and for fiscal year 2004 could
approach $1.2 billion. On the positive side, the state's unemployment rate of
4.8% continued to run below the national average of 5.7% as of January 2003. The
state's current long-term general obligation debt rating remained strong in the
AA range by all three of the major rating agencies.

Investment Strategy

For the six-month period ended March 31, 2003, the short-term municipal market
experienced two distinct segments. Initially, short-term municipal yields moved
higher as a result of unusually heavy supply in the short end of the yield
curve. One-year note yields that began the period in the 1.45% range rose to the
1.75% area, while the average variable rate yield rose from 1.55% to 1.85%.
However, from early November 2002 through period end, the increased uncertainty
surrounding international events and strong asset inflows into the short end of
the yield curve strengthened

*     Based on a constant investment throughout the period, with dividends
      compounded daily, and reflecting a net return to the investor after all
      expenses.


                                                                               1


demand for these municipal securities. This higher demand lowered the yield on a
one-year fixed coupon note to the 1.10% range, while the average variable rate
yield fell to the 1.15% range by period end. We maintained the Fund's average
portfolio maturity in a neutral range of 30 days-35 days. This investment
strategy was appropriate in light of growing global uncertainties. Additionally,
the flat nature of the short-term yield curve offered little incentive to
implement a more aggressive investment stance.

Within the portfolio, fixed coupon securities with maturities predominately in
the three-month - six-month range remained an important diversification tool and
provided an avenue to secure attractive yields through the first quarter of
2003. During this time, average variable rate yields, which adjust on a daily or
weekly basis, fell to a period low of .95%-1.00% because of strong demand. The
Fund's fixed coupon securities, which included municipal notes and tax-exempt
commercial paper, comprised approximately 35% of the Fund's assets during the
period and performed especially well as variable rate yields moved lower.
Finally, the Fund's portfolio strategy and asset allocation for the six-month
period ended March 31, 2003 provided shareholders with a well-diversified
portfolio of high credit quality securities and a stable net asset value.

Looking forward, we will continue to monitor budget developments in Connecticut
as we anticipate that state and local government short-term borrowing needs over
the next 18 months will exceed current levels and could place significant upward
pressure on Connecticut-specific short-term yields.

In Conclusion

We thank you for your continued support of CMA Connecticut Municipal Money Fund,
and we look forward to serving your investment needs in the months and years
ahead.

Sincerely,

CMA CONNECTICUT MUNICIPAL MONEY FUND
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1. Significant Accounting Policies:

CMA Connecticut Municipal Money Fund (the "Fund") is part of CMA Multi-State
Municipal Series Trust (the "Trust"). The Fund is registered under the
Investment Company Act of 1940 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 following is
a summary of significant accounting policies followed by the Fund.

(a) Valuation of investments -- Investments are valued at amortized cost, which
approximates market value. For the purpose of valuation, the maturity of a
variable rate demand instrument is deemed to be the demand notice payment
period. In the case of a floating rate instrument, the remaining maturity is the
next coupon date on which the interest rate is to be adjusted.

(b) 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.

(c) 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. Interest income (including amortization of premium and
discount) is recognized on the accrual basis.

(d) Prepaid registration fees -- Prepaid registration fees are charged to
expense as the related shares are issued.

(e) Dividends and distributions to shareholders -- The Fund declares dividends
daily and reinvests daily such dividends (net of non-resident alien tax and
backup withholding tax withheld) in additional fund shares at net asset value.
Dividends are declared from the total of net investment income, excluding
discounts earned other than original issue discounts. Net realized capital
gains, if any, are normally distributed annually after deducting prior years'
loss carryforward. The Fund may distribute capital gains more frequently than
annually in order to maintain the Fund's net asset value at $1.00 per share.

(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.

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
based upon the average daily value of the Fund's net assets, at the following
annual rates: .50% of the first $500 million of average daily net assets; .425%
of average daily net assets in excess of $500 million but not exceeding $1
billion; and .375% of average daily net assets in excess of $1 billion.

Pursuant to the Distribution and Shareholder Servicing Plan in compliance with
Rule 12b-1 under the Investment Company Act of 1940, Merrill Lynch, Pierce,
Fenner & Smith


                                                                               9


CMA CONNECTICUT MUNICIPAL MONEY FUND
NOTES TO FINANCIAL STATEMENTS (CONCLUDED)
- --------------------------------------------------------------------------------

Incorporated ("MLPF&S") receives a distribution fee from the Fund at the end of
each month at the annual rate of .125% of average daily net assets of the Fund.
The distribution fee is to compensate MLPF&S financial advisors and other
directly involved branch office personnel for selling shares of the Fund and for
providing direct personal services to shareholders. The distribution fee is not
compensation for the administrative and operational services rendered to the
Fund by MLPF&S in processing share orders and administering shareholder
accounts.

Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of ML & Co., is
the Fund's transfer agent.

For the year ended March 31, 2003, the Fund reimbursed FAM $11,114 for certain
accounting services.

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

3. Shares of Beneficial Interest:

The number of shares sold, reinvested and redeemed during the years corresponds
to the amounts included in the Statements of Changes in Net Assets for net
proceeds from sale of shares, value of shares reinvested and cost of shares
redeemed, respectively, since shares are recorded at $1.00 per share.

4. Distributions to Shareholders:

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

- --------------------------------------------------------------------------------
                                                   3/31/2003           3/31/2002
- --------------------------------------------------------------------------------
Distributions paid from:
  Tax-exempt
    income .............................          $3,849,638          $9,213,493
                                                  ----------          ----------
Total distributions ....................          $3,849,638          $9,213,493
                                                  ==========          ==========
- --------------------------------------------------------------------------------

As of March 31, 2003, there were no significant differences between the book and
tax components of net assets.

5. Capital Loss Carryforward:

At March 31, 2003, the Fund had a net capital loss carryforward of approximately
$54,408 of which $33,851 expires in 2006 and $20,557 expires in 2008. This
amount will be available to offset like amounts of any future taxable gains.

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of CMA Connecticut Municipal Money Fund as of March

responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our

We conducted our audits in accordance with auditing standards generally accepted

perform the audit to obtain reasonable assurance about whether the financial

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 March 31, 2003, by correspondence with the custodian. 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 CMA
Connecticut Municipal Money Fund as of March 31, 2003, the results of its
