Eadulf III or Eadwulf III (died 1041) was the earl of Bernicia from 1038 until his death. He was a son of Uhtred the Bold and succeeded his brother Ealdred. According to the Anglo-Saxon Chronicle, he was betrayed by King Harthacnut and killed. He was the last of the ancient Bernician line of earls to rule before his son Osulf usurped the Northumbrian earldom in 1067.
