Eadulf, Eadwulf, or occasionally Adulf, surnamed Evil-child (Old English: Yfelcild), (fl. AD 963–973) was an Anglo-Saxon nobleman and Earl of Bamburgh in the late tenth century. Although Eadwulf is sometimes described as the Earl of Northumbria, he ruled only the northern portion of Northumbria from the River Tees to possibly as far north as the Firth of Forth. Eadwulf was one of the noblemen present at King Edgar's council at Chester which formally granted Lothian to the Scots.
