Three Sides Live is the third live album by the English rock band Genesis, released as a double album on 4 June 1982 on Charisma Records in the United Kingdom. It was released by Atlantic Records in the United States. After touring in support of their studio album Abacab ended in December 1981 the band entered an eight-month break in activity, during which they selected recordings from their previous tours for a live album. Three Sides Live includes recordings between 1976 and 1981; the UK edition contains additional live tracks on the fourth side of the double LP, while the original international edition featured tracks from their 1982 EP 3×3 and B-sides from Duke. Subsequent international reissues have adopted the UK track sequence.

A double album is an audio album that spans two units of the primary medium in which it is sold, typically either records or compact disc. A double album is usually, though not always, released as such because the recording is longer than the capacity of the medium. Recording artists often think of double albums as being a single piece artistically; however, there are exceptions, such as John Lennon's Some Time in New York City and OutKast's Speakerboxxx/The Love Below . Since the advent of the compact disc, albums are sometimes released with a bonus disc featuring additional material as a supplement to the main album, with live tracks, studio out-takes, cut songs, or older unreleased material. One innovation was the inclusion of a DVD of related material with a compact disc, such as video related to the album or DVD-Audio versions of the same recordings. Some such discs were also released on a two-sided format called DualDisc.
