Joe Cahill (; 19 May 1920 – 23 July 2004) was a prominent figure in the Irish republican movement in Northern Ireland and former chief of staff of the Provisional Irish Republican Army (IRA). He joined a junior-republican movement, Na Fianna Eireann, in 1937 and the following year, joined the Irish Republican Army. In 1969, Cahill was a key figure in the founding of the Provisional Irish Republican Army. During his time in the Provisional IRA, Cahill helped import weapons and raise financial support. He served as the chief of staff in 1972, but was arrested the following year when a ship importing weapons was intercepted. After his release, he continued to serve on the IRA Army Council and lead all financial dealings for Sinn Féin. In the 1990s, the IRA and Sinn Féin began to work on seeking peace. Cahill served on the council that called a cessation on 21 July 1997. Cahill attended several of the talks that finally led to the Good Friday Agreement on 10 April 1998.

Cahill's grandparents were neighbours of the Scottish-born Irish socialist and Easter Rising leader James Connolly, who co-founded the Irish Citizens Army.
