Newry River and River Clanrye are names for one of the rivers of Ireland; it passes through the city of Newry and empties into Carlingford Lough near Warrenpoint. The River which runs through Newry, forms the historic border between County Armagh and County Down. Some maps call the portion downstream from Newry to the Lough the 'Newry River' and the portion upstream of Newry the 'Clanrye' (as it curls around to its sources in the foothills of the Mourne Mountains in Ulster), but not all sources make this distinction.
