Rosguill ( Irish language and official name: Ros Goill) is a peninsula situated in north-north-west County Donegal, Ireland. Lying between the peninsulae of Fanad to the east and Horn Head to the west, Rosguill is a dichotomy of heathland and ocean. With the great Sheephaven Bay with its mellow waters and pure-white strands on the one hand, and the treacherous sand banks of Mulroy Bay on the other. Between, a mixture of bog, hill and pastureland, the ancient walls, remnants of cattle enclosures, and the various evidences of fortification are proof of the area's use since antiquity. The Parish of Rosguill is an alternative name for the Parish of Mevagh, which covers the peninsula and an equally sized hinterland.
There are nearly 800 people living in Rosguill ED and 33% of residents are native Irish speakers.
