"Sleepwalk" is a song by Ultravox, released on 20 June 1980 as the first single from their fourth album Vienna, and their first with Midge Ure as frontman.

[2] "Sleepwalk" was the first song the band recorded with Midge Ure February 1980 at RAK Studios, London.

The original version was later remixed May 1980 at Conny's Studio in Cologne for inclusion on the band's album Vienna.

The single's B-side, "Waiting" is a more solemn, bass-laden affair in comparison to the faster synth work of the A-side.

It now appears on the CD re-issue of Vienna as a bonus track, as well as various other Ultravox compilations.
