Alexander of Islay or Alexander MacDonald was a medieval Scottish nobleman, who succeeded his father Domhnall of Islay as Lord of the Isles (1423–1449) and rose to the rank of Earl of Ross (1437–49). His lively career, especially before he attained the earldom of Ross, led Hugh MacDonald, the 17th century author of History of the MacDonalds, to commemorate him as "a man born to much trouble all his lifetime". Alexander allied himself with King James I of Scotland against the power of the Albany Stewarts in 1425 but, once the Albany Stewarts were out of the way, Alexander quickly found himself at odds with the new king. War with King James would initially prove Alexander's undoing, and would see the King's power in Scotland greatly increased, but at the Battle of Inverlochy Alexander's army prevailed against the forces of the King. Alexander died in 1449, having greatly extended his family's landed wealth and power. He was buried, not in the Isles of his ancestors, but at Fortrose Cathedral in his mainland Earldom of Ross.
