Rory Naismith is Professor of Early Medieval English History at the University of Cambridge, and a Fellow of Corpus Christi College, Cambridge. He studied at the University of Cambridge in the Department of Anglo-Saxon, Norse and Celtic, and taught at King's College London before returning to his current position in Cambridge.

Rory is interested in the history of England and its neighbours in Britain and Europe between the fifth and eleventh centuries.

He has worked on a number of areas, many of them involving economic and social history. Major recent projects have examined the reign of Offa of Mercia (757-96), the making and use of money across early medieval Europe, the earliest guilds, towns and the remarkable sources for tenth- and eleventh-century history preserved at the monasteries of Ely and Ramsey.
