"When We Was Fab" is a song by English musician George Harrison, which he released on his 1987 album Cloud Nine. It was also issued as the second single from the album, in January 1988. The lyrics serve as a nostalgic reflection by Harrison on the days of Beatlemania during the 1960s, when the Beatles were first referred to as "the Fab Four". Harrison co-wrote the song with Jeff Lynne, who also co-produced the track. The recording references the psychedelic sound that the Beatles had helped popularise in 1967, through its use of sitar, cello, and backwards-relayed effects. Harrison's former Beatles bandmate Ringo Starr is among the other musicians on the track. The single was accompanied by an innovative music video, directed by the partnership of Kevin Godley and Lol Creme. One of Harrison's most popular songs, "When We Was Fab" has appeared on the compilations Best of Dark Horse 1976–1989 (1989) and Let It Roll (2009).

Cloud Nine is the eleventh studio album by the English rock musician George Harrison. The album was recorded and released in 1987 after Harrison had taken a five-year hiatus from his career as a solo artist. The hit single "Got My Mind Set on You" from this album re-established Harrison as a critically acclaimed and commercially significant recording artist. Cloud Nine was Harrison's final solo studio album to be released during his lifetime; his next album Brainwashed was released in 2002, almost a year after his death.
