Trial & Retribution is a feature-length ITV police procedural television drama series that first aired on 19 October 1997.

Written and devised by Lynda La Plante as a follow-on from her successful television series Prime Suspect, each episode was typically broadcast over two nights.

David Hayman stars as the main protagonist of the series, DCS Michael "Mike" Walker.

The first seven series each contained two two-hour long episodes, covering one feature-length story.

However, due to special programming regarding the September 11 attacks, the programme was removed from the schedule and was not rescheduled for broadcast until June 2002.
