"Tin Soldier" is a song released by the English rock band Small Faces on 2 December 1967, written by Steve Marriott (credited to Marriott/Lane).

The song signalled a return to the band's R&B roots whilst continuing their forays into psychedelic rock and other musical experiments.

When Tin Soldier was released the BBC informed the band that the last line of the song had to be removed from all TV and radio broadcasts, mistakenly believing that Marriott sang "sleep with you", when in fact the lyric is "sit with you".

[9] In 1997, some 30 years after the song's original release, Mojo voted "Tin Soldier" the tenth-best single of all time, in a readers' poll.

The song has been covered by Quiet Riot, Lou Gramm, Uriah Heep, Streetheart, Todd Rundgren, The Guess Who, Paul Weller, Transatlantic, and Humble Pie (which also featured Marriott).
