Iye Mackay, 4th of Strathnaver

Iye Mackay, 4th of Strathnaver, was chief of Clan Mackay in the Highlands, succeeding his father Donald Mackay, 3rd of Strathnaver. His long feud with the Earl of Sutherland ended in 1370, when he and his eldest son and heir Donald were murdered at Dingwall Castle by the earl's party.

His daughter Mariota married Alexander Stewart, Earl of Buchan, the Wolf of Badenoch. Since Donald died with him, the chiefship passed to his grandson Angus Mackay.
