The counties of Ireland (Irish: Contaetha na hÉireann) are historic administrative divisions of the island into thirty-two units. They began as Norman structures, and as the powers exercised by the Cambro-Norman barons and the Old English nobility waned over time, new offices of political control came to be established at a county level.

Upon the partition of Ireland in 1921, six of the traditional counties became part of Northern Ireland. In Northern Ireland, counties ceased to be longer used for local government in 1973; districts are instead used. In the Republic of Ireland, some counties have been split resulting in the creation of new counties: there are currently 26 counties, 3 cities and 2 cities and counties that demarcate areas of local government in the Republic.
