County Fermanagh (IPA: /fɚr'mænɘ/; Contae Fhear Manach or Fear Manach in Irish), is the westernmost of the six counties that form Northern Ireland, and the westernmost part of the United Kingdom. It is part of the province of Ulster. Fermanagh is often referred to as Ireland's Lake District. The county is approximately 120 km (75 mi) from Belfast and 160 km (99 mi) from Dublin.

The name Fermanagh is an anglicization of Fhear Manach which means 'Place of the Men of the Manacháin tribe' so named after their chief O'Manacháin (Anglicized as O'Monaghan), the famous warrior monk.

In Northern Ireland the county borders County Tyrone to the north-east, and in the Republic of Ireland the county borders County Monaghan to the south-east, County Cavan and County Leitrim to the south-west and County Donegal to the north-west. Fermanagh is the only county of Northern Ireland that does not border Lough Neagh.
