Prior to the 1885 United Kingdom general election the area was part of the Donegal constituency.
From 1922, on the establishment of the Irish Free State, it was not represented in the UK Parliament.
This constituency comprised the northern part of County Donegal, consisting of the barony of Inishowen East, that part of the barony of Inishowen West not contained within the constituency of East Donegal, and that part of the barony of Kilmacrenan contained within the parishes of Clandavaddog, Killygarvan and Tullyfern and the townlands of Drumherrive, Glenalla and Ray in the parish of Aughnish.
