Seán McCool was a prominent Irish Republican and a former chief of staff of the Irish Republican Army. Imprisoned on numerous occasions, both North and South of the border, he embarked on a number of hunger strikes in order to secure release. During the 1930s, McCool was one of the few socialists to remain in the IRA after the Republican Congress's decision to split. He stood as a candidate for the Irish Republican party Clann na Poblachta before leaving them as a result of their decision to go into government with Fine Gael.
McCool joined Seán MacBride's Clann na Poblachta, a political party which attempted to push Irish Republicanism back into the Irish political mainstream

Several people are reported to have served as Chief of Staff of the Irish Republican Army in the organisations bearing that name. Due to the clandestine nature of these organisations, this list is not definitive.
