The Pagan Middle Ages is an academic anthology edited by the Belgian historian Ludo J.R. Milis. Containing eight papers by various Dutch and Belgian historians and archaeologists, it is devoted to the study of how various pre-Christian religious beliefs and practices survived and were absorbed into the new, Christian society in Europe during the Middle Ages. It was first published by the Institut Historique Belge de Rome in 1991 under the Dutch title of De Heidense Middeleeuwen and subsequently translated into English by Tanis Guest and published by The Boydell Press in 1998.
