Jimmy Steele (August 8, 1907 – August 9, 1970) was an Irish republican and Irish Republican Army (IRA) member born in Belfast, Ireland.
Steele joined Fianna Éireann in 1920 during the Irish War of Independence and later went on to join the IRA. He was arrested in 1923 and again in 1924 and imprisoned in Crumlin Road Gaol. After his release in 1925, Steele helped in the reorganisation of the IRA's Belfast Brigade.
In 1935 Steele led an IRA raid on a RUC base within the grounds of Campbell College, a school in the east of the city. The raid was unsuccessful due to a tip-off, but Steele managed to escape. The following year he was arrested for the raid along with several other IRA members and again sent to Crumlin Road Gaol. In 1943 Steele, along with Patrick Donnelly, Ned Maguire and Hugh McAteer escaped from the Gaol. Shortly afterwards he was appointed adjutant of the Northern Command. While on the run he helped 21 prisoners escape from jail on March 20, 1943, this was known as The Big Derry Jail Escape.
Steele spent a further ten years in prison after arrests in late 1943 and 1967. He wrote for a number of republican publications, including Glor Uladh, Resurgent Ulster and An Phoblacht. In the 1950 United Kingdom general election Steele stood for Sinn Féin in the West Belfast constituency.
Steele was founder of the Belfast Republican Press Centre in 1970. He was the first editor of Republican News, which started as a monthly and later became a weekly.
