Trust is a British television crime drama, written by Richard McBrien and directed by David Drury, that was first broadcast on ITV on 4 May 1999. Originally broadcast in two parts, and also re-cut into three episodes for international broadcast, Trust stars Mark Strong as psychiatrist Michael Mitcham, who is accused of the murder of one of former patients, with whom he fathered a child. Meanwhile, his wife, Anne (Caroline Goodall), a successful solicitor, begins an affair with Michael's best friend, Andrew (Nathaniel Parker), who brings Michael's credibility into question during the trial for the crimes he is accused of.

The film was broadcast on BBC America on 1 January 2007 as the first in a series of five British thrillers previously unbroadcast in the United States. The film was also released on DVD in Germany in 2004, but this remains the only home video release to date. Notably, the DVD features audio dubbing in German, rather than subtitles.
