Eadwulf III of Bamburgh or Eadwulf Cudel or Cutel (meaning cuttlefish) (died early 1020s) was ruler of Bamburgh for some period in the early eleventh century. Following the successful takeover of York by the Vikings in 866/7, southern Northumbria became part of the Danelaw, but in the north English rulers held on from a base at Bamburgh. They were variously described as kings, earls, princes or high-reeves, and their independence from the kings of England and Scotland is uncertain. Uhtred the Bold and Eadwulf Cudel were sons of Waltheof, ruler of Bamburgh, who died in 1006. He was succeeded by Uhtred, who was appointed by Æthelred the Unready as earl in York, with responsibility for the whole of Northumbria. Uhtred was murdered in 1016, and king Cnut then appointed Erik, son of Hakon, earl at York, while Eadwulf succeeded at Bamburgh.
