Aftermath, first released on 15 April 1966, by Decca Records is the fourth British studio album by The Rolling Stones. It was released in the United States on 20 June 1966 by London Records as their sixth American album. The album proved to be a major artistic breakthrough for The Rolling Stones, being the first full-length release by the band to consist exclusively of Mick Jagger/Keith Richards compositions. Aftermath was also the first Rolling Stones album to be recorded entirely in the United States, at the legendary RCA Studios in Hollywood, California at 6363 Sunset Boulevard, and the first album the band released in stereo.

The album is also notable for its musical experimentation, with Brian Jones playing a variety of instruments not usually associated with rock music—including sitar on "Paint It, Black", the Appalachian dulcimer on "Lady Jane" and "I Am Waiting", the marimbas (African xylophone) on "Under My Thumb" and "Out of Time," harmonica on "High and Dry" and "Goin' Home", as well as guitar and keyboards. The songwriting featured some of the Stones' most overtly misogynistic lyrics and, though full of experiments as noted above, much of the music was still rooted in Chicago electric blues.

In 2002, the US edition of Aftermath was ranked number 108 on the List of Rolling Stone's 500 Greatest Albums of All Time.
In August 2002 both editions of Aftermath were reissued in a new remastered CD and SACD digipak by ABKCO Records.
