The Irish Republican Socialist Party or IRSP (Irish: Páirtí Poblachtach Sóisialach na hÉireann) is a republican socialist party active in Ireland. It is often referred to as the "political wing" of the Irish National Liberation Army (INLA) paramilitary group and claims the legacy of socialist revolutionary James Connolly, who founded the Irish Socialist Republican Party in 1896 and was executed after the Easter Rising of 1916.
