The Worker's Party of Ireland (WPI) was a communist party in Ireland. It was founded in 1926 by former members of the Communist Party of Ireland (CPI) and other communists. Among its members were Roddy Connolly (son of James Connolly), who served as party leader, Nora Connolly (daughter of James Connolly), Tom Lyng, the trade unionist P. T. Daly, Walter Carpenter Jnr, and Jack White. Many of the members had been active in Jim Larkin's Irish Worker League, and the party attempted to affiliate with the Communist International in place of the IWL.
