Ceolwulf of Northumbria was an eighth-century sovereign who ruled the kingdom of Northumbria from 729 to 737. Born around 695 as the son of Cutha, he succeeded Osric and experienced a brief period of deposition before regaining his throne. He was a significant patron of the church, notably providing gifts to the Lindisfarne monastery. After relinquishing his royal authority to Eadberht, he entered the monastic life at Lindisfarne, where he lived until his death in late 764 or early 765.
