Spiral Circus is the name of the first live album by British psychedelic rock/progressive rock band Porcupine Tree from their first tour. The tracks were recorded directly from the mixing desk in three locations of England during December 1993. The first half of the album was taken from the shows in the BBC and The Borderline, London, and the second half from The Nag's Head, High Wycombe.

Spiral Circus was first released in 1994 on cassette only. This tape was given away free to subscribers of the Transmission information service. It was then reissued on vinyl in 1997 limited to 500 copies. Both editions are deleted at the present.{{cite web|url =http://www.voyage-pt.de/swdisco.pdf|title =Steven Wilson -The Complete Discography (7th Edition), p. 32| accessdate =2008-03-23}}

Despite the fact that the track is not included, the album name is a reference to a section in the song "The Sky Moves Sideways Phase 1" from The Sky Moves Sideways.
