A Saucerful of Secrets is the second studio album by the English rock band Pink Floyd. It was recorded at EMI's Abbey Road Studios on various dates from August 1967 to April 1968 and was released on 29 June 1968, through EMI Columbia in the United Kingdom, while the album was released on 27 July 1968 in the United States by Tower.

The album was recorded before and after Syd Barrett's departure from the group. Owing to Barrett's behaviour becoming increasingly unpredictable, David Gilmour was recruited in January 1968. As a result, A Saucerful of Secrets became the only non-compilation Pink Floyd album on which all five band members appeared, the first for Gilmour, with him appearing on five songs ("Let There Be More Light", "Set the Controls for the Heart of the Sun", "Corporal Clegg", "A Saucerful of Secrets" and "See-Saw"), and the last for Barrett, with him on three ("Remember a Day", "Jugband Blues" and "Set the Controls for the Heart of the Sun"). "Set the Controls for the Heart of the Sun" was the only song all five members appeared on together. Drummer Nick Mason declared A Saucerful of Secrets his favourite Pink Floyd album.
