"If I Say Yes" is a 1986 single by British pop group Five Star, and was the follow-up to their biggest-ever UK single, the #2 ranked "Rain or Shine".

It was the fourth release from the group's Silk & Steel album.

A 3:43 remixed version of the song (an edit of the cassette-only "Lew Hahn New York Remix"), which was the version released in the U.S., appeared on the group's 1989 Greatest Hits album.

Jim Reid of Record Mirror considered "If I Say Yes" a "typically bubbling disco-pop" song very similar to Five Star's previous singles, "with a sax solo, silly clothes and plenty of big grins".
