The Earl of Fife or Mormaer of Fife was the ruler of the province of Fife in medieval Scotland, which encompassed the modern counties of Fife and Kinross. Due to their royal ancestry, the earls of Fife were the highest ranking nobles in the realm, and had the right to crown the king of Scots.
Held by the MacDuff family until it passed by resignation to the Stewarts, the earldom ended on the forfeiture and execution of Murdoch Stewart in 1425. The earldom was revived in 1759 with the style of Earl Fife for William Duff, a descendant of the MacDuffs. His great-great-grandson, the 6th Earl Fife, was made Earl of Fife in 1885 and Duke of Fife in 1889.
