Prologue is the third studio album by the English progressive rock band Renaissance, released in October 1972.

The new members added at this point were bassist Jon Camp, drummer Terence Sullivan and guitarist Mick Parsons.

Electric guitarist Rob Hendry was brought in at the last minute to replace him for the recording sessions of June and July 1972, and left the band soon after the album was completed.

The original double LP with gatefold sleeve included the complete Prologue, but one song from Ashes was edited.

In 2018 Esoteric Recordings announced a re-mastered and expanded edition of the first Haslam era album which was released on the 28 September 2018.
