In planning and performing our audits of the
financial statements of Vanguard High-Yield Tax-
Exempt Fund, Vanguard Intermediate-Term Tax-
Exempt Fund, Vanguard Limited-Term Tax-
Exempt Fund, Vanguard Long-Term Tax-Exempt
Fund, Vanguard Municipal Money Market Fund,
Vanguard Ultra-Short-Term Tax-Exempt Fund,
and Vanguard Tax-Exempt Bond Index Fund
(constituting Vanguard Municipal Bond Funds,
hereafter collectively referred to as the "Funds")
as of and for the year ended October 31, 2023, in
accordance with the standards of the Public
Company Accounting Oversight Board (United
States) (PCAOB), 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 N-CEN, 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 Funds 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
company's 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
company's 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
company are being made only in accordance with
authorizations of management and directors of
the company; and (3) provide reasonable
assurance regarding prevention or timely
detection of unauthorized acquisition, use or
disposition of a company's 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
company's 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 PCAOB. 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 a material weakness as defined
above as of October 31, 2023.

This report is intended solely for the information
and use of the Board of Trustees of Vanguard
Municipal Bond Funds and the Securities and
Exchange Commission and is not intended to be
and should not be used by anyone other than
these specified parties.
