County Clare is a county in the province of Munster in the Southern part of the republic of Ireland, bordered on the west by the Atlantic Ocean. Clare County Council is the local authority. The county had a population of 127,938 at the 2022 census. The county seat and largest settlement is Ennis.

There are four provinces of Ireland: Connacht, Leinster, Munster and Ulster. The Irish word for this territorial division, cúige, meaning "fifth part", suggests that there were once five, and at times Meath has been considered to be the fifth province. In the medieval period, however, there were often more than five. The number of provinces and their delimitation fluctuated until 1610, when they were permanently set by the English administration of James I. The provinces of Ireland no longer serve administrative or political purposes but function as historical and cultural entities.
