Patrick Joseph Kelly, commander of the East Tyrone Brigade of the Provisional Irish Republican Army during the mid-1980s, is born in Carrickfergus, County Antrim, Northern Ireland, on March 19, 1957. He holds the position until his death in a Special Air Service (SAS) ambush at Loughgall, County Armagh in May 1987.

Kelly is the oldest child in a Roman Catholic family of five. He lives in Carrickfergus until he is sixteen, at which time the family returns to live in Dungannon. His uncle is the Irish Republican activist and elected official Liam Kelly.

Kelly becomes a member of the Provisional Irish Republican Army at the beginning of the 1970s and becomes one of the most experienced IRA men in County Tyrone. He is arrested in February 1982 based on testimony from an informant named Patrick McGurk but is released in October 1983 due to lack of evidence, after a trial that lasts fifteen minutes.

In 1985, Kelly becomes brigade commander in East Tyrone and begins developing tactics for attacking isolated Royal Ulster Constabulary (RUC) bases in his area. Under his leadership the East Tyrone Brigade becomes the most active IRA unit.

In 1986, Kelly attends the IRA Army Convention where the main topic of discussion is the principle of abstentionism. Gerry Adams and others argue that the abstentionist rule should be dropped and the Provisional movement should become involved in constitutional politics. Kelly votes against dropping the rule, and a rift with the majority of the IRA Army Council ensues.

Kelly is killed by the Special Air Service (SAS) on May 8, 1987, while he is participating in an attack on Loughgall police station, in which seven other IRA men, Pádraig McKearney, Declan Arthurs, Seamus Donnelly, Tony Gormley, Eugene Kelly, Jim Lynagh, and Gerard O’Callaghan, also die. His funeral in Dungannon is one of the largest in Tyrone during the Troubles.

Kelly is buried in Edendork Cemetery, two miles from his home in Dungannon.
