Carraig Airt is a small Gaeltacht village in the Barony of Kilmacrenan to the north of County Donegal, Ireland.
The village is on the R245 route between Letterkenny and Creeslough. Situated as it is at the base of the Rosguill peninsula, in one of the more remote but most scenic parts of the country, the village provides services for a large hinterland, with a supermarket with banking facilities, a post office, a doctor's surgery and a barracks manned part-time by An Garda Síochána.
Carrigart has a public park that borders the shoreline behind the houses on the main street. Designed by Angela Gallagher, it is maintained by the Tidy Towns Committee and has won several awards.
The village and its environs remain largely agricultural, relying heavily on passing trade and tourism during the summer months. In common with the rest of this part of Donegal, Carrigart has a large number of second homes, owned especially by Northern Irish holiday makers.
