The Provisional Government of Ireland (Irish: Rialtas Sealadach na hÉireann) was the provisional government for the administration of Southern Ireland from 16 January 1922 to 5 December 1922. It was a transitional administration for the period between the ratification of the Anglo-Irish Treaty and the establishment of the Irish Free State. Its legitimacy was disputed by the Anti-Treaty members of Dáil Éireann.
