Imagine: John Lennon is a soundtrack album of popular music composed by John Lennon for the 1988 documentary film, Imagine: John Lennon. Originally released that year as a double album, it now remains available on one CD.

Bridging his two musical phases together, as a member of The Beatles and a solo artist (similar to George Harrison's earlier The Best of George Harrison), Imagine: John Lennon is a career-spanning collection of Lennon's many musical highlights. In addition there are a couple of heretofore unreleased recordings: an acoustic demo of "Real Love" taped in 1979 (an alternate recording of which would be finished by The Beatles for 1996' s Anthology 2) and a rehearsal take of "Imagine" in mid-1971 before the final take was captured. It also features for the first time a clean-intro version of "A Day in the Life", that would appear later on the CD release of The Beatles' 1967–1970 compilation.

Imagine: John Lennon, with its wealth of stock Lennon footage and self-narration, proved to be a well-received film and its soundtrack sold well in the US, reaching #31 and going gold. In the UK, the album peaked at #64.

The project arrived at a timely juncture and was successful in thwarting the then-released The Lives of John Lennon by Albert Goldman, a controversial and reputation-tarnishing book which many dismissed as fiction, including Ono and Lennon's close friends, as well as the remaining Beatles.
