The North East Liberties of Coleraine (named after Coleraine town) is a barony in County Londonderry, Northern Ireland. It borders the north-Londonderry coastline, and is bordered by three other baronies: Coleraine to the west; Dunluce Lower to the north-east; Dunluce Upper to the south-east. The North East Liberties of Coleraine formed the north-western part of the medieval territory known as the Route. The area was part of County Antrim from 1584 to 1613, when it became part of the new County Londonderry.
