Muff (from Irish Magh)[2] is a village, civil parish and townland in County Donegal, Ireland.

Muff was one of several Protestant villages in eastern Donegal that would have been transferred to Northern Ireland, had the recommendations of the Irish Boundary Commission been enacted in 1925.

[3] Muff has experienced significant growth in population during the last decade as people from Northern Ireland migrate across the border.

[citation needed] The village has a primary school, Scoil Naomh Bríd, which has slightly over 200 students enrolled.

Each summer, usually during the first week in August, the village celebrates Muff Festival;[8] which includes céilidhs, competitions, street parties, parades, amusements, night-time entertainment, and live performances.
