               Re:  The UBS Funds
                    File Nos. 33-47287 and 811-6637

Ladies and Gentlemen:

     Pursuant to Rule 497(j) under the Securities Act of 1933, as amended,  this
letter serves as  certification  that the form of Prospectuses and Statements of
Additional  Information  that would have been filed under  paragraph (c) of Rule
497 would not have differed  from those  contained in  Post-Effective  Amendment
Nos. 54/55 to the Registration  Statement of The UBS Funds, which was filed with
the Securities and Exchange Commission electronically on October 27, 2006.

     Please  direct  questions or comments  relating to this filing to me at the
above-referenced telephone number.

                                            Very truly yours,


                                            /s/ Jana L. Cresswell
                                            Jana L. Cresswell
