Harald Maddadsson (Old Norse: Haraldr Maddaðarson, Gaelic: Aralt mac Mataid) (c. 1134 – 1206) was Earl of Orkney and Mormaer of Caithness from 1139 until 1206. He was the son of Matad, Mormaer of Atholl, and Margaret, daughter of Earl Haakon Paulsson of Orkney. Of mixed Norse and Gaelic blood, and a descendant of Scots kings,[1] he was a significant figure in northern Scotland, and played a prominent part in Scottish politics of the twelfth century. The Orkneyinga Saga names him one of the three most powerful Earls of Orkney along with Sigurd Eysteinsson and Thorfinn Sigurdsson.[2]
