Eardulf of Lindisfarne (died 900) was Bishop of Lindisfarne for 46 years between 854, following the death of his predecessor, and his own death in 899. He was chiefly responsible for removing the remains of St Cuthbert from Lindisfarne to protect them from Viking invasions, eventually resettling them in Chester-le-Street and temporarily running the see from there. During their seven years of wandering with Cuthbert's remains the monks were also known to have visited Galloway and stayed in a cave now known as St Cuthbert's Cave near Dunstanburgh Castle in Northumberland.
