"Tempus Fugue-it" (also known as "Tempus Fugit") is a 1949 jazz composition by jazz pianist Bud Powell (1924–1966). It has been recorded by Powell, Miles Davis and many others. The song is not actually a fugue in compositional form; its title is a pun on the Latin phrase tempus fugit, meaning "time flies". The name is also a reflection of the speed at which the piece is played.
