"(Shake, Shake, Shake) Shake Your Booty" is a song recorded and released in 1976 by KC and the Sunshine Band for the album Part 3. The song became their third number-one hit on the Billboard Hot 100, as well as their third number-one on the Hot Soul Singles chart. The song was met with a degree of controversy, since the lyrics were interpreted or likely speculated by many as having sexual connotations. However, according to KC, it had a lot more meaning and depth. During his performance he would witness the entire crowd having a good time except for some minority. The song inspired people to "get off their can and get out there and do it". The B-side of Shake Your Booty was "Boogie Shoes", which later became a hit on its own when it appeared on the Saturday Night Fever soundtrack in 1977.

"(Shake, Shake, Shake) Shake Your Booty" holds the record for being the only number-one song title with a word repeated more than three times in it. The chorus consists of the title expression with the word "shake" appearing eight times.
