TO OUR SHAREHOLDERS:


For the year ended March 31, 2003, CMA North Carolina Municipal
Money Fund paid shareholders a net annualized yield of .76%.* As of
March 31, 2003, the Fund's 7-day yield was .53%.


Economic Environment
North Carolina's finances remained under pressure throughout the
year ended March 31, 2003. Consequently, in August 2002, Moody's
Investors Service downgraded the state's general obligation rating
from AAA to Aa1, citing continued structural imbalance, reliance on
non-recurring revenues and a weakening balance sheet. In the past
few years, the state endured a series of adverse events in the form
of costly legal judgements, rebuilding in the wake of floods and
hurricanes, and revenue loss resulting from the national economic
recession. Income trends were impacted by the weak economy. After
growing 8% in 2000, personal income growth fell to just over 3% in
2002.

During the past year, North Carolina increased its sales tax rate
and made other revenue adjustments intended to restore structural
balance to the current year's budget. In addition, the state has
been reacting to budget imbalance since fiscal 2001 and has always
taken timely action to balance its budget. Despite these measures,
North Carolina has continued to struggle with revenue shortfalls. As
a result, by fiscal year-end 2003, the state's Budget Stabilization
Fund is projected to have no remaining funds. In early spring,
Governor Mike Easly will present the fiscal 2004 budget. The state
again will be facing a sizeable budget gap because several of the
revenue enhancement measures approved in 2001 are expiring. In
addition, budget reserves have been depleted and other non-recurring
measures were utilized to balance fiscal 2003. In fiscal 2004, the
current estimated budget deficit ranged anywhere from $1.7 billion
to $2.0 billion or as much as 15% of the state's budget. The state
has not disclosed whether or not it is contemplating the
securitization of tobacco settlement revenues to help reduce its
budget deficit. The long-term prospects for the state continue to be
good as a result of its expanding and diversifying economy.
Moreover, although outstanding debt has grown during the past few
years, debt levels remain well below the national average.


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



Going forward, a wide spread surplus of labor is expected to put
little upward pressure on wages and restrict income growth until
late 2003. The state's exporters have felt the pinch of the global
economic slowdown during 2002 with exports in the second half of the
year falling by nearly 20% compared to a year ago, far worse than
the 6% decline experienced nationwide. State exports of computer and
electronic products were hit particularly hard, decreasing by more
than 15% over the same period. During the past decade, North
Carolina's population increased by 19.3%, reaching 8 million. This
population growth has been stronger than the nation as a whole as
well as for the region. Consequently, the state's housing market
remains generally well balanced as lower mortgage rates continue to
have a favorable impact on home sales and new construction. Looking
ahead, the housing sector is expected to stay strong as a slow
economic recovery keeps interest rates relatively low.


Investment Strategy
At the beginning of the 12-month period ended March 31, 2003, we
sought to maintain the Fund's relatively bearish stance. This was
because of our expectation of a rise in interest rates as reflected
by the Federal Reserve Board's change in bias from that of weakness
to neutral at the March 19, 2002 Federal Open Market Committee
meeting. In addition, this position allowed the Fund to take
advantage of the anticipated rise in yields on variable rate product
caused by outflows during tax time. As tax season began, a smaller
amount of income tax related redemptions caused variable rate
product to underperform compared to previously purchased fixed rate
securities. Consequently, although we allowed the Fund to trend to a
more bearish position, we continued to benefit from the more
aggressive stance attained early in the first quarter of 2002.

As the period progressed, economic data began to reveal that growth
for the second quarter of 2002 was slowing from that of the first
quarter. Furthermore, U.S. equity markets were suffering from a
confidence crisis caused by accounting scandals and corporate
malfeasance. For example, the Dow Jones Industrial Average, which
began the period at 10,362, declined to 7,992 by the end of March
2003. As a result of these factors, we looked to move to a more
neutral position given our opinion that the Federal Reserve Board
would not tighten monetary policy in the coming months. A majority
of our extension took place in April and May 2002 as we tried to
lock in higher yields than were expected going forward. This
strategy benefited the Fund as yields on tax-exempt securities
maturing in one year declined almost 70 basis points (.70%) by the
end of June 2002. As summer ended, continued weakness in capital
expenditures and another possible military confrontation with Iraq
caused the U.S. economy to weaken. In fact, at its August 13, 2002
Federal Open Market Committee meeting, the Federal Reserve Board
changed its outlook from neutral back to that of weakness.

As the second half of the period began, we looked to maintain the
Fund's current stance because it was our opinion that the
significant short-term issuance from the State of California would
cause general market variable rate product to outperform fixed rate
securities through year end. Our strategy benefited the Fund as
yields on variable rate product averaged 1.65%, while yields on
fixed rate product averaged 1.45% through mid-November.
Nevertheless, from mid-November 2002 to early March 2003, yields on
variable rate securities declined significantly because of the
tremendous demand for short-term tax-exempt instruments. This was
caused by both the Federal Reserve Board lowering the Federal Funds
rate by 50 basis points at the November 6, 2002 Federal Open Market
Committee meeting and continued cash inflows through February 2003.
Since we anticipated that the Federal Reserve Board would keep
monetary policy on hold for the near term, we continued to look for
attractive opportunities to moderately extend our average portfolio
maturity during this time. However, this proved to be difficult
given a flat short-term tax-exempt yield curve and lack of state-
specific fixed rate issuance. Our strategy allowed the Fund to
provide a total return that was above average relative to its peer
group for the one-year period ended March 31, 2003. As the period
ended, we planned to maintain our current position, given the
significant rally in the note market and the expected spike in
yields on variable rate product as tax time approaches.


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

CMA NORTH CAROLINA MUNICIPAL MONEY FUND
NOTES TO FINANCIAL STATEMENTS


1. Significant Accounting Policies:
CMA North Carolina 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 back-up 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.

(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 $10,344 has been reclassified
between paid-in capital in excess of par and accumulated net
realized 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.



CMA NORTH CAROLINA MUNICIPAL MONEY FUND
NOTES TO FINANCIAL STATEMENTS (CONCLUDED)


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 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 consultants
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 $6,841
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
periods 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                $  2,487,924       $  5,398,800
                                    ------------       ------------
Total distributions                 $  2,487,924       $  5,398,800
                                    ============       ============



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 $33,623 of which $6,425 expires in 2005; $26,651
expires in 2007 and $547 expires in 2008. This amount will be
available to offset like amounts of any future taxable gains.



CMA NORTH CAROLINA MUNICIPAL MONEY FUND
INDEPENDENT AUDITORS' REPORT


To the Shareholders and Board of Trustees
of CMA North Carolina Municipal Money Fund
of CMA Multi-State Municipal Series Trust:

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