James Larkin (Irish: Séamas Ó Lorcáin; 21 January 1876 – 30 January 1947), sometimes known as Jim Larkin, was an Irish republican, socialist and trade union leader. He was one of the founders of the Irish Labour Party, Irish Transport and General Workers' Union, Workers' Union of Ireland (the two unions later merged to become SIPTU, Ireland's largest trade union) and the Irish Citizen Army (a paramilitary group which was integral to both the Dublin Lockout and the Easter Rising).
