Dún Lúiche, known in English as Dunlewey or Dunlewy, is a small Gaeltacht village in the Gweedore district in the north-west of County Donegal in Ulster, the northern province in Ireland. The village sits in the Poisoned Glen, at the foot of Errigal and on the shore of Dunlewey Lough. The Cronaniv Burn flows along the southern edge of the village. Dunlewey has a tourist centre, called the Lakeside Centre or Ionad Cois Locha, which offers boat trips of the lake. To the west of the lake is a ruined church.
