"Free as a Bird" is a song originally written and recorded in 1977 as a home demo by John Lennon, formerly of the Beatles. In 1995, 25 years after their break-up and 15 years after Lennon was murdered, the band released a studio version incorporating contributions from his surviving bandmates Paul McCartney, George Harrison and Ringo Starr.

The single was released as part of the promotion for The Beatles Anthology video documentary and the Anthology 1 compilation album. For the Anthology project, McCartney asked Lennon's widow Yoko Ono for unreleased material by Lennon to which the three remaining ex-Beatles could contribute. "Free as a Bird" was one of two such songs (along with "Real Love") for which McCartney, Harrison, and Starr contributed additional instrumentation, vocals, and arrangements. Jeff Lynne, who had worked with Harrison on Harrison's album Cloud Nine and as part of the Traveling Wilburys, co-produced.

The song peaked at No. 2 on the UK Singles Chart and No. 6 on the US Billboard Hot 100. It also became a top-ten hit in at least 10 other countries, including Australia, Canada, Hungary and Sweden. It won the 1997 Grammy Award for Best Pop Performance by a Duo or Group with Vocal and was the Beatles' 34th top-ten single in the United States, meaning they had at least one top-forty hit in four different decades.

The music video was produced by Vincent Joliet and directed by Joe Pytka. Shot from the point of view of a bird in flight, it references numerous Beatles songs.
