"Sister Morphine" is a song written by Marianne Faithfull, Mick Jagger and Keith Richards.

After a legal battle Faithfull retained her rights as a co-author, acknowledged by the 1994 Virgin Records reissue of the Stones' album catalogue from Sticky Fingers through Steel Wheels.

[5] In 2018, Faithfull told writer Kris Needs that the song was “my self-portrait in a dark mirror, my miniature gothic masterpiece, my celebration of death.”[7] In the United Kingdom, Faithfull's single was withdrawn by Decca due to the drug reference in the title, after an estimated 500 copies had been issued, but in other countries the single remained in release.

[8] In addition, the French, US and Netherlands editions of the single actually featured alternate versions of both sides to the UK release.

[9] The song remains a staple of her concert set-list and appeared on the live albums Blazing Away in 1990[10] and No Exit in 2016.
