RE:      VANGUARD MALVERN FUNDS
         FILE NO. 33-23444


Dear Mr. Sandoe,

         The following responds to your comments of April 14, 2008 on the
post-effective amendment of the registration statement of the above-referenced
registrant. You commented on Post-Effective Amendment No. 35 that was filed on
February 26, 2008.

     COMMENT:  The  biography  of William E. Ricks on page 13 of the U.S.  Value
Fund prospectus  states that "[h]e has worked in investment  management with AXA
Rosenberg since 1989,  . . . ." Please state more precisely what Mr. Ricks was
doing.

     RESPONSE:  We have  amended Mr.  Ricks'  biography  to state that "[h]e has
worked  in  investment  management  with AXA  Rosenberg  since  1989,  including
trading, operations, portfolio engineering, and portfolio construction."

     COMMENT:  The chart on pp.  28-29 of the SAI,  which  shows  the  principal
occupations and  directorships  of the fund's  trustees,  does not reference the
fact that each fund  trustee  is also a director  of The  Vanguard  Group,  Inc.
(Vanguard).

     RESPONSE: This fact is stated at the bottom of pg. 27, so it is unnecessary
to restate it for each of the trustees in the chart. (This is why the heading of
that  particular  column of the chart  refers to  "outside"  rather than "other"
directorships.)

     COMMENT: Why aren't all of the funds' trustees  "interested" given that all
of them serve as directors of Vanguard?

     RESPONSE:  A trustee of a fund would be an interested person of the fund if
he or she was an  interested  person  of the  fund's  principal  underwriter  or
investment adviser.

     o    None of the fund  trustees  serves on the board of, or is otherwise an
          interested  person  of,  the funds'  principal  underwriter,  Vanguard
          Marketing Corporation.  And even if they did so serve, Vanguard has an
          exemption from Section 2(a)(19), the definition of "interested person"
          for such service.  See In the Matter of The Vanguard  Group,  Inc., et
          al., 47 SEC 450, Inv. Co. Act Release No. 11645 (Feb. 25, 1981).

     o    Although fund trustees are also Vanguard directors, Vanguard is not an
          investment adviser of any of the Malvern Funds - or ANY Vanguard fund.
          Although  Vanguard  provides advisory services to some Vanguard funds,
          it does so at cost.  Pursuant to Section  2(a)(20)  of the  Investment
          Company Act, the definition of "investment  adviser" "does not include
          . . . (iii) a company furnishing [advisory] services at cost to one or
          more investment companies . . . ."

     COMMENT:  Text on Page B-36 of the SAI, under the heading  "Description  of
Compensation," states that the portfolio manager's bonus is determined, in part,
by how  closely the manager  tracks the fund's  benchmark  index over a one-year
period.  Please clarify whether the manager's  performance is based on a pre-tax
or post-tax basis.

     RESPONSE:  We will amend this discussion to indicate that the comparison is
based on the manager's pre-tax performance and to make other minor changes.

     COMMENT:  Text on page B-38 of the SAI, under the heading  "Description  of
Compensation,"  states  that a  Vanguard  portfolio  manager's  base  salary "is
determined by the manager's  experience and performance in the role, taking into
account the ongoing  compensation  benchmark  analyses performed by the Vanguard
Human Resources  Department." Please identify a peer group or benchmark to which
manager's compensation is compared.

     RESPONSE: We believe the information requested is not required and that the
text in its current form sufficiently  informs  prospective  investors as to how
the manager's base salary is determined.

     COMMENT: TANDY REQUIREMENTS
- ------------------------------------
As required by the SEC, the Funds acknowledge that:

                o The Fund is responsible for the adequacy and accuracy of the
                  disclosure in the filing.
                o Staff comments or changes in response to staff comments in the
                  filings reviewed by the staff do not foreclose the Commission
                  from taking any action with respect to the filing.
                o The Fund may not assert staff comments as a defense in any
                  proceeding initiated by the Commission or any person under the
                  federal securities laws of the United States.


Sincerely,



Barry A. Mendelson
Principal
The Vanguard Group, Inc.
