Thorne is a British crime drama television series, based on the novels of author Mark Billingham, that was first broadcast on Sky One on 10 October 2010. A single six-episode series, starring David Morrissey in the title role of Detective Inspector Tom Thorne, was broadcast at 21:00 on Sundays until 14 November. As well as Morrissey, the series also stars Aidan Gillen, Eddie Marsan, O-T Fagbenle and Lorraine Ashbourne in supporting roles. The series comprises two three-part dramatisations of the first two Thorne novels, Sleepyhead and Scaredycat. Sleepyhead, directed by Stephen Hopkins, previewed in full at the BFI Southbank in London on 4 October 2010, followed by a Q&A session featuring writer Mark Billingham and actors David Morrissey and Eddie Marsan.

Although directly adapted from the novels, there are notable differences in the series, including: Brigstocke's gender has been changed; Dave Holland's ethnicity has been changed; and Phil Hendricks is portrayed as a short, partly tattooed Irishman with a full head of hair, a juxtaposition of the tall, bald, heavily pierced, heavily tattooed Mancunian described in Billingham's novels. In the United States, Encore broadcast all six episodes of the series across two nights. Sleepyhead and Scaredycat aired on 12 and 13 June 2012 respectively. The series is also available as a complete box set from Netflix. All six episodes were released on Region 2 DVD and Blu-ray on 10 January 2011.
