Re: Fidelity Defined Trusts, Series F (the "Trust")
Ladies/Gentlemen:
Pursuant to the requirements of Rule 497(j) of the General Rules and
Regulations of the Securities Act of 1933, as amended, the form of prospectus
which would have been filed pursuant to Rule 497(b) of the General Rules and
Regulations of the Securities Act of 1933, as amended, would not have differed
from that contained in Amendment No. 1 to the Registration Statement for the
above referenced Trust, the most recent amendment, filed electronically with the
Securities and Exchange Commission of May 13, 1998.
Very truly yours,
National Financial Services
Corporation
