Tyrconnell or Tirconnell (Irish: Tír Chonaill, meaning "Land of Conall") was a political state in north-west Ireland up till 1601. It lay in the area now more commonly referred to as County Donegal, although the kingdom and later principality of Tyrconnell was broader than that, including parts of Sligo, Leitrim (in present-day Republic of Ireland), Tyrone, Fermanagh and a southern part of Londonderry (in present-day Northern Ireland).
