Report of Independent Registered Public Accounting Firm


To the Trustees and Shareholders of Putnam Money Market Fund:

In planning and performing our audit of the financial
statements of Putnam Money Market Fund (the Fund) as of and
for the year ended September 30, 2011, in accordance with the
standards of the Public Company Accounting Oversight Board
(United States), we considered the Funds internal control over
financial reporting, including controls over safeguarding
securities, as a basis for designing our auditing procedures
for the purpose of expressing our opinion on the financial
statements and to comply with the requirements of Form NSAR,
but not for the purpose of expressing an opinion on the
effectiveness of the Funds internal control over financial
reporting.  Accordingly, we do not express an opinion on the
effectiveness of the Funds internal control over financial
reporting.

The management of the Fund is responsible for establishing and
maintaining effective internal control over financial
reporting.  In fulfilling this responsibility, estimates and
judgments by management are required to assess the expected
benefits and related costs of controls.  A funds internal
control over financial reporting is a process designed to
provide reasonable assurance regarding the reliability of
financial reporting and the preparation of financial
statements for external purposes in accordance with generally
accepted accounting principles.  A funds internal control over
financial reporting includes those policies and procedures
that (1) pertain to the maintenance of records that, in
reasonable detail, accurately and fairly reflect the
transactions and dispositions of the assets of the company;
(2) provide reasonable assurance that transactions are
recorded as necessary to permit preparation of financial
statements in accordance with generally accepted accounting
principles, and that receipts and expenditures of the fund are
being made only in accordance with authorizations of
management and trustees of the company; and (3) provide
reasonable assurance regarding prevention or timely detection
of unauthorized acquisition, use or disposition of a funds
assets that could have a material effect on the financial
statements.

Because of its inherent limitations, internal control over
financial reporting may not prevent or detect misstatements.
Also, projections of any evaluation of effectiveness to future
periods are subject to the risk that controls may become
inadequate because of changes in conditions, or that the
degree of compliance with the policies or procedures may
deteriorate.

A deficiency in internal control over financial reporting
exists when the design or operation of a control does not
allow management or employees, in the normal course of
performing their assigned functions, to prevent or detect
misstatements on a timely basis.  A material weakness is a
deficiency, or a combination of deficiencies, in internal
control over financial reporting, such that there is a
reasonable possibility that a material misstatement of the
Funds annual or interim financial statements will not be
prevented or detected on a timely basis.

Our consideration of the Funds internal control over financial
reporting was for the limited purpose described in the first
paragraph and would not necessarily disclose all deficiencies
in internal control over financial reporting that might be
material weaknesses under standards established by the Public
Company Accounting Oversight Board (United States).  However,
we noted no deficiencies in the Funds internal control over
financial reporting and its operation,

including controls over safeguarding securities, that we
consider to be material weaknesses as defined above as of
September 30, 2011.

This report is intended solely for the information and use of
management and the Board of Trustees of Putnam Money Market
Fund and the Securities and Exchange Commission and is not
intended to be and should not be used by anyone other than
these specified parties.
