The Mormaer or Earl of Buchan (/mɔːrˈmɛr/, /ˈbʌxən/) was originally the provincial ruler of the medieval province of Buchan. Buchan was the first Mormaerdom in the High Medieval Kingdom of the Scots to pass into the hands of a non-Scottish family in the male line. The earldom had three lines in its history, not counting passings from female heiresses to sons. Today it is held by the Erskine family as a peerage. The current holder is Malcolm Erskine, 17th Earl of Buchan (b. 1930).
