YesYears is a 1991 video retrospective of the progressive rock group Yes covering the band's entire history from their 1969 debut album through their 1991 release Union. The video features interviews with the entire band, which, at the time of filming, featured eight members (Jon Anderson, Steve Howe, Trevor Rabin, Tony Kaye, Rick Wakeman, Chris Squire, Bill Bruford, and Alan White).
It was released in conjunction with an audio set also entitled Yesyears featuring songs spanning the band's career up until 1991. Oddly enough, no song from Yes' debut album appears in this rockumentary. The video was originally released on VHS, and reissued on DVD in 2003.
