"The Piper at the Gates of Dawn" is the debut studio album by the English rock band Pink Floyd, and the only one made under founding member Syd Barrett's leadership. The album, named after the title of chapter seven of Kenneth Grahame's "The Wind in the Willows" and featuring a kaleidoscopic cover photo of the band taken by Vic Singh, was recorded from February to May 1967 and released on 4 August 1967. It was produced by Beatles engineer Norman Smith and released in 1967 by EMI Columbia in the United Kingdom and Tower in the United States, in August and October respectively.

The release of the album in the US was timed with the band's tour of the US. The US version of the album has a rearranged tracklist. This version omits "Astronomy Domine", "Flaming", and "Bike" and contains the UK non-album single, "See Emily Play".

Since its release, the album has been hailed a pivotal psychedelic rock album, with the embryonic elements of what was to become progressive rock. In 1973, it was packaged with the band's second album, "A Saucerful of Secrets", and released as "A Nice Pair" to introduce new fans to the band's early work after the success of "The Dark Side of the Moon".

"The Piper at the Gates of Dawn" was voted 347th on Rolling Stone magazine's list of the "500 Greatest Albums of All Time".
