Eric John (1922–2000) was a reader in history at the University of Manchester and a specialist in Anglo-Saxon history. He was described by James Campbell as "one of the most distinguished and provocative of Anglo-Saxonists" D. H. Farmer described his studies of the English Benedictine Reform, mainly in pages 154-264 of Orbis Britanniae, as "both stimulating and provocative; even those who cannot assent to all his conclusions recognise that he has brought a new dimension to the study of the reform".
His books included:
He also contributed chapters on the later Anglo-Saxon period in The Anglo-Saxons (1982), edited by James Campbell; and "The Social and Political Problems of the Early English Church" in Anglo-Saxon History: Basic Readings (2000) edited by David Pelteret.
