	Re:	Pioneer Series Trust V (File Nos. 333-129005; 811-21823)
		Registration Statement on Form N-1A

Ladies and Gentlemen:

      In connection with the review by the Staff of the Securities and Exchange
Commission (the "Commission") of Post-Effective Amendment No. 25 to the
Registration Statement on Form N-1A of Pioneer Series Trust V (the
"Registrant"), with respect to its series Pioneer Long/Short Bond Fund, the
Registrant acknowledges that, with respect to filings made by the Registrant
with the Commission and reviewed by the Staff:

(a)   the Registrant is responsible for the adequacy and accuracy of the
      disclosure in the filings;

(b)   Staff comments or changes to disclosure 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 filings; and

(c)   the Registrant 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,

Pioneer Series Trust V
