"Interstellar Overdrive" is an instrumental composition written and performed by the English rock band Pink Floyd. The song was written in 1966 and is on their 1967 debut album, The Piper at the Gates of Dawn, clocking in at almost ten minutes in length.^[2][3] It features long sections of free-form instrumental improvisation reflective of the group's live performances.

The song originated when guitarist Syd Barrett heard the band's manager Peter Jenner humming a song, which Barrett tried to interpret by playing it on his guitar. Sharing the same emphasis on chromaticism with "Astronomy Domine", the piece was recorded in several takes during March and April 1967. An earlier, longer recording of the song made in January 1967 is available on the EP London '66–'67, a sample of which can be heard on the soundtrack to the film Tonite Let's All Make Love in London, which was recorded at Sound Technique Studios in early 1967 and was released in the same year. An even earlier version was made in October 1966 and can be heard in the 1968 film San Francisco. Other versions of the track appear on various bootleg recordings. The piece has been covered by acts such as Tyrannosaurus Rex (jammed on bass by Steve Peregrin Took live in 1969), Pearl Jam, Camper Van Beethoven, Hawkwind, the Melvins, moe., and Simon House.
