"Wash" is a Pearl Jam song which originally appeared as a B-side on the "Alive" single. It also appeared on the "Alive" promotional CD and cassette that were released prior to the commercial single release, and as an extra track on European releases of Ten.

The song was a Ten outtake and one of the very first songs the band wrote. According to guitarist Stone Gossard in the Lost Dogs liner notes, the song was written instantaneously.

"Wash" later appeared on the 2003 Pearl Jam B-Sides and rarities compilation Lost Dogs. The version on Lost Dogs is a completely different version from the b-side.

A live performance of "Wash" can be found on the Live at the Gorge 05/06 box set.
