       Application to withdraw post-effective amendment to Registration
       Statement on Form N-1A (File Nos. 333-89354 and 811-21108)

Ladies and Gentlemen:

Pursuant to Rule 477(a) of Regulation C under the Securities Act of 1933, as
amended, Pioneer Fundamental Growth Fund (the "Registrant") hereby applies for
the Commission's consent to the withdrawal of a post-effective amendment to a
registration statement on Form N-1A pertainig to Pioneer International Equity
Fund, incorrectly filed under the Registrant's registration number, File No.
333-89354, on July 29, 2008 (SEC Accession No. 0001174520-08-000007) (the

Pioneer International Equity Fund is a different registrant. The
Amendment was filed under the Registrant's registration number as a result of a
clerical error. No securities of Pioneer Fundamental Growth Fund were sold in
connection with the Amendment.

Kindly forward any questions about this application to the undersigned at
