RE:      Vanguard Specialized Funds
         File No. 2-88116

Dear Mr. Sandoe,

         This letter responds to your telephone comments of May 8, 2007 on
Post-Effective Amendment No. 64 to the registration statement of the
above-referenced registrant, which was filed on March 23, 2007.


Comment 1:     Energy Fund Prospectus - Primary Investment Strategies
- --------------------------------------------------------------------------------
Comment:       The first sentence of the primary investment strategies
               section states that the fund "invests at least 80% of its
               assets in the common stocks of companies principally engaged
               in energy-related activities, such as production and
               transmission of energy or energy fuels; the making of
               component products for such activities, energy research; and
               energy conservation or pollution control." Explain whether the
               use of "such as" means that non-energy-related activities are
               included in the 80% figure.

Response:      The 80% figure includes common stocks of companies principally
               engaged in energy-related activities. "Such as" is used to
               describe examples of such activities.


Comment 2:     Energy Fund Prospectus - Capitalization
- --------------------------------------------------------------------------------
Comment:       Item 4 of the prospectus states that most stocks held by the fund
               are mid- and large-capitalization stocks.  Discuss the risks of
               mid- and large-cap stocks in the primary risks section.

Response:      The fund's strategy is focused on stocks in a particular industry
               and is not centered on a particular market capitalization.
               Accordingly, we have not added market cap disclosure to the
               fund's primary investment strategies. In a broadly diversified
               stock fund, a bias toward small- and/or mid-cap stocks is a risk
               factor worth noting. However, in funds that are focused on a
               single

               industry or sector, there is a relatively low correlation
               between fund performance and style benchmark performance. The
               risk attributable to the fund's focus dwarfs the risk
               attributable to the capitalization of the stocks owned.

Comment 3:     Energy Fund Prospectus - Plain Talk about the Fund's Portfolio
               Managers
- --------------------------------------------------------------------------------
Comment:       Please clarify the role played by the various portfolio managers.

Response:      Vanguard uses the term "co-manage" to describe relationships
               where portfolio managers are truly equals with respect to
               managing portfolio assets. We will provide additional
               clarification as necessary when there are distinctions to be
               made between the roles and responsibilities of a fund's
               portfolio managers. However, since there are no such
               distinctions in the case of this fund, we prefer to leave the
               descriptions unchanged.

Comment 4:     Investment in Other Investment Companies
- --------------------------------------------------------------------------------
Comment:       The Statement of Additional Information states that each fund
               may invest in other investment companies to the extent
               permitted by the Investment Company Act of 1940. For each fund
               that invests in other investment companies, do the indirect
               expenses incurred by the investing fund exceed 0.01%?

Response:      Certain funds invest in other investment companies, but in all
               cases the indirect expenses incurred by the investing fund are
               less than 0.01%.

As required by the SEC, each fund acknowledges 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,
                                   /s/Sarah A. Buescher
