Chain was Edinburgh musician Paul Haig's third album and was released in May 1989 on Circa Records, a subsidiary of Virgin Records.

The album was co-produced by long-time Haig cohort, Alan Rankine, instrumentalist with celebrated Dundee band, The Associates.  There was another Associates connection on the album - the track "Chained" was written by Haig's good friend, Billy Mackenzie.  Haig returned the favour and gave Mackenzie the track "Reach The Top" for his album "The Glamour Chase", which after many years in limbo was finally released in 2002.
