Malcolm Fleming, Earl of Wigtown († 1363) was the son of Robert Fleming, a Stewart vassal and holder of the lands of Fulwood and Cumbernauld, who died sometime before 1314. He was the "foster-father" of King David II of Scotland and became the first man to hold the title Earl of Wigtown. Malcolm was given the barony of Kirkintilloch forfeited from the Comyns by King Robert I of Scotland during the First War of Scottish Independence and received other lands in Lennox and Wigtownshire. Malcolm became Sheriff of Dumbarton and keeper of the castle thereafter.
