Torrens Knight (born 4 August 1969) is a Northern Ireland loyalist, who belonged to the North Antrim and Londonderry Brigade of the Ulster Defence Association (UDA). In 1993 he took part in two mass murders in County Londonderry: the Greysteel massacre (in which eight civilians were shot dead) and the Castlerock killings (in which three civilians and a Provisional Irish Republican Army (IRA) member were killed). After being convicted—along with three others—for the killings, he served seven years in the Maze Prison before his release in 2000 under the terms of the Good Friday Agreement.
