Carlingford Lough is a glacial fjord or sea inlet in northeastern Ireland, forming part of the border between Northern Ireland to the north and the Republic of Ireland to the south. On its northern shore is County Down, the Mourne Mountains, and the town of Warrenpoint; on its southern shore is County Louth, the Cooley Mountains and the village of Carlingford. The Newry River flows into the loch from the northwest.

Warrenpoint is a small port town and civil parish in County Down, Northern Ireland. It sits at the head of Carlingford Lough, south of Newry, and is separated from the Republic of Ireland by a narrow strait. The town is beside the village of Rostrevor and is overlooked by the Mournes and Cooley Mountains. Warrenpoint sprang up within the townland of Ringmackilroy, and is locally nicknamed "The Point", which also represents the town's full name in Irish, An Pointe".
