"She's a Rainbow" is a song by the English rock band The Rolling Stones and was featured on their 1967 album Their Satanic Majesties Request.

Written by Mick Jagger and Keith Richards, "She's a Rainbow" was recorded on 18 May 1967. It is most famous for its vibrant piano by Nicky Hopkins, Brian Jones' use of the mellotron, and its rich lyricism by Jagger.

John Paul Jones, later of Led Zeppelin, arranged the strings of this song during his session days. Despite rumours, none of The Beatles perform on this track. Backing vocals were by Jagger and Richards.

The lyrics in the chorus share the phrase "she comes in colours" with the song of that title by Love released in December 1966.

The song uses humorous devices such as when the strings play out of tune and off key towards the end of the song. Also, the rest of the Stones are singing their "La La's" like little children. The song ends on an unusual sour electric guitar chord.

It was released as a single in December 1967 and went to #25 in the United States. It is included on a large number of the Stones' hits compilations that cover this period, including Forty Licks. It was performed occasionally on the 1997–98 Bridges to Babylon Tour. Apple Inc. used this song in an advertisement for the iMac G3. Later Sony used the song in an advert for BRAVIA.
