"Overground" is a song by English post-punk band Siouxsie and the Banshees. It was originally featured on the Banshees' debut studio album, The Scream (1978). The band re-recorded the track with elaborate, lush orchestral instrumentation with a flamenco acoustic guitar for its inclusion on the four-track extended play The Thorn (1984). This version was released as a single the same year by record label Polydor.
