Harry's Game is a British television drama mini-series made by Yorkshire Television for ITV in 1982, closely based on the 1975 novel of the same name by Gerald Seymour. Apart from brief scenes, it is set in and around Belfast in the Troubles. Its lead actors were Ray Lonnen and Derek Thompson.

The British government cabinet minister Henry Danby is murdered by an IRA gunman, Billy Downes, in front of his wife and children as he leaves for work. Downes then escapes to Belfast and army officer Harry Brown is sent undercover into Belfast's Catholic community to track down the assassin.[2] Brown is chosen for the mission because he is an Ulsterman who has previously done similar work in Oman.

Given the cover identity of merchant seaman Harry McEvoy, he finds lodgings in the Falls Road area and secures a job in a scrapyard. He dates a Catholic, Josephine Laverty, and unknowingly encounters Downes in a local club, which is raided by the British Army. A British soldier recognises Harry but ignores him and arrests Downes, who is interrogated but set free. Harry tips off his superiors that the killer was at the club and that Theresa, a girl at whose family home Billy stayed the night while on the run, knows his name. Theresa is arrested, but caught between the police interrogator Rennie and her fear of the IRA if she talks, she hangs herself in prison before revealing Downes' identity. When Josephine realises that Harry must have passed on the information about Theresa, she tells him to leave while he can, but he refuses, saying Danby's killer cannot be allowed to get away with the murder
