"Jeepster" is a song by English glam rock act T. Rex. It was released on 5 November 1971 by record label Fly as a single from the group's sixth studio album (and second as T. Rex) Electric Warrior. The B-side, "Life's a Gas", is taken from the same album.

"Jeepster" was released as a single on 5 November 1971 by record label Fly. The single peaked at No. 2 in the UK Singles Chart, and was controversial in that Fly Records released the song without singer Marc Bolan's prior permission, Bolan having just left Fly for EMI, which had given him control of his own label T. Rex Wax Co. Records.

The music and rhythm are similar to that of the Howlin' Wolf song "You'll Be Mine", written by Willie Dixon. In interviews, Marc Bolan has acknowledged that he "lifted it from a Howlin' Wolf song". "Jeepster" has also similarities with Roy Orbison's song "You're My Baby" (written by Johnny Cash).
