Bishop of Dunwich (ancient)

The Bishop of Dunwich is an episcopal title which was first used by an Anglo-Saxon bishop between the seventh and ninth centuries and is currently used by the suffragan bishop of the Diocese of St Edmundsbury and Ipswich. The title takes its name after Dunwich in the English county of Suffolk. Previously a significant port, this town has now largely been lost to the sea.

In about 630 or 631 a diocese was established by St. Felix for the Kingdom of the East Angles, with his episcopal seat initially, briefly established at Soham before being transferred to Dunwich on the Suffolk coast. There is a possibility the unidentified Dommoc may be Dunwich, but this is yet to be proved. In 672 the diocese was divided into the sees of Dunwich and Elmham by St. Theodore, Archbishop of Canterbury.

The line of bishops of Dunwich continued until it was interrupted by the Danish Viking invasions in the late ninth and early tenth centuries. By the mid 950s the sees of Dunwich and Elmham were reunited under one bishop, with the episcopal see at Elmham.
