For other uses, see Donegal (disambiguation) County Donegal (Irish: Contae Dhún na nGall) is a county in the northwest of Ireland. It is one of three counties in the province of Ulster that does not form part of Northern Ireland. The name "Donegal" comes from the Irish, meaning "the fort of the foreigners". The county was named after the former administrative centre of Donegal Town. When first created, it was sometimes referred to as County Tyrconnel (Irish: Tír Chonaill), after the Tyrconnel earldom it succeeded. Calling the whole county Tír Conaill is technically incorrect as the Inishowen peninsula (Irish: Inis Eoghain) was historically distinct from Tír Chonaill.
