Fanad is a peninsula that lies between Lough Swilly and Mulroy Bay on the north coast of County Donegal in Ireland.
The origins of the name Fanad are lost in time though there is some speculation that the name derives from an old Gaelic word Fana for “sloping ground”. It is also referred to as Fannet or Fannett in older records.
Fanad encompasses the parishes of Clondavaddog, Killygarvan and parts of Tullyfern and Aughinish.
It measures approximately 25 km north-south measured from Fanad Head to the town of Ramelton and approximately 12 km east-west measured between the townlands of Doaghbeg and Glinsk.
The southern boundary of Fanad has been the subject of some dispute over the centuries. In the 16th century, during the time of the MacSuibhnes as rulers of Fanad, it was stated that the territory of Fanaid stretched as far south as the River Lennon between Kilmacrennan and Ramelton.
