Ailtirí na hAiséirghe was a minor fascist political party in Ireland, founded by Gearóid Ó Cuinneagáin in March 1942. The party sought to form a totalitarian Irish Christian corporatist state and its sympathies were with the Axis powers in World War II. It was one of a wave of minor far-right parties in 1940s Ireland, like the Irish Monetary Reform Association, that failed to achieve mainstream success.

Gearóid Ó Cuinneagáin was an Irish language activist, nationalist and far-right politician born in Belfast, Ireland. He was the founder and leader of Ailtirí na hAiséirghe, a fascist party which sought to create a Christian corporatist state and revive the Irish language through the establishment of an authoritarian dictatorship in Ireland.
