Kieran Doherty, Irish republican hunger striker and politician who serves as a Teachta Dála (TD) for the Cavan–Monaghan constituency from June 1981 to August 1981, dies on August 2, 1981 in HM Prison Maze (known to republicans as Long Kesh) on the 73rd day of his hunger strike. He is a volunteer in the Belfast Brigade of the Provisional Irish Republican Army (IRA).

Doherty is the third son in a family of six. He is born on October 16, 1955 in the Andersonstown area of Belfast and is educated at St. Theresa’s Primary School and Glen Road Christian Brothers School (CBS). The Doherty brothers are known cyclists and sportsmen in the Andersontown area. He wins an Antrim Gaelic football medal at minor level in 1971.

Doherty joins Fianna Éireann in 1971 and is interned by the British Government between February 1973 and November 1975. His brothers Michael and Terence are interned between 1972 and 1974.

Doherty works as an apprentice heating engineer. His girlfriend is Geraldine Scheiss and, although they never become formally engaged, they become very close toward the end of his life. Before his arrest, she had not known that he is in the IRA.

In August 1976, while he is out to set a bomb, the van in which he is riding is chased by the Royal Ulster Constabulary (RUC). During the chase Doherty manages to leave the van and hijack a car. He later ditches the car and is found one mile away from the car. He is convicted and sentenced to 18 years for possession of firearms and explosives, with another four years for the hijack.

Doherty starts his hunger strike on May 22, 1981. While on hunger strike he is elected as an Anti H-Block TD for the Cavan–Monaghan constituency at the 1981 Irish general election, which is held on June 11. He receives 9,121 (15.1%) first preference votes and is elected on the fourth count. The two seats gained by Anti H-Block candidates denies Taoiseach Charles Haughey the chance to form a government, and the 22nd Dáil Éireann sees a Fine Gael–Labour Party coalition government come to office, with Garret FitzGerald as Taoiseach.

Doherty dies at the age of 25 on August 2, 1981. He lasts 73 days on hunger strike, the longest of the 1981 hunger strikers, and only one day short of Terence MacSwiney. He is the shortest-serving Dáil deputy ever, serving as a TD for only two months.

Doherty is commemorated on the Irish Martyrs Memorial at Waverley Cemetery in Sydney, Australia. In October 2016, a painting of him is unveiled in Leinster House by Sinn Féin.
