Thorir Hund (Old Norse: Þórir hundr, Modern Norwegian: Tore Hund) (born ca. 990) was one of the greatest chiefs in Hålogaland. Tore Hund was one of the leaders of the Stiklestad peasant faction opposing Norwegian King Olaf II of Norway, later named St. Olaf. He was reported to have been among the chieftains who killed the king in the Battle of Stiklestad in 1030. He also served in the forces of King Canute the Great on several occasions.
