"Pictures of Lily" is a single by the British rock band the Who, written by guitarist and primary songwriter Pete Townshend.

In 1971, "Pictures of Lily" was included in the Who album Meaty Beaty Big and Bouncy, a compilation of previously released singles.

According to Pete Townshend in the 2006 book Lyrics by Rikky Rooksby, "the idea was inspired by a picture my girlfriend had on her wall of an old Vaudeville star – Lily Bayliss [sic].

However, in his 2012 memoir Who I Am, Townshend mentioned Lillie Langtry, the music hall star and mistress of Edward VII, as the inspiration for the tune.

It returned to make a one-off appearance at a show in Passaic, New Jersey on 11 September 1979, where singer Daltrey forgot the lyrics and they went straight to Free's "All Right Now", which the band performed on rare occasions in the 1970s.

He filmed the band recording the song, showing the four bandmates performing, with Keith Moon being recruited for the high notes in the song (even though Pete Townshend can be heard telling Keith he "keeps jumping on John's part", however, other live video footage shows John Entwistle, the band's bassist, harmonising and playing the French Horn.
