Anthony John Selvidge (born 11 January 1945), known professionally as Tony Kaye, is an English keyboardist, songwriter, producer and manager, best known as a founding member of the progressive rock band Yes. Born into a musical family, Kaye was classically trained and intended to become a concert pianist before he developed an interest in jazz and contemporary rock and pop music. He joined several groups through the 1960s, including the Federals, Johnny Taylor's Star Combo, Jimmy Winston & His Reflections, and Bittersweet.

From 1968 to 1971, Kaye was a member of Yes and played on their first three albums. He then formed Badger and relocated to Los Angeles in 1974, after which he toured with David Bowie and joined Detective. Kaye then played in Badfinger and is featured on their final studio album in 1981. He returned to Yes in 1983 for their most commercially successful period before he left in 1994.

Kaye has since been involved with several projects with Billy Sherwood and is a current member of CIRCA:. From 2009 to 2011, the two were also members of the supergroup Yoso with members of Toto. In 2017, Kaye was inducted into the Rock and Roll Hall of Fame as a member of Yes.
