John Mitchel (Irish: 'Seán Mistéal'; 3 November 1815 – 20 March 1875) was an activist for Irish nationalism, author, and political journalist. Born in Camnish, near Dungiven, County Londonderry, he became a leading member of both Young Ireland and the Irish Confederation. He also became an editorial voice for the Southern viewpoint in the Confederate States of America in the 1860s. He was elected to the House of Commons in 1875, but was disqualified because he was a convicted felon.
