Deddington is a civil parish in Oxfordshire about 6 miles (10 km) south of Banbury. The 2011 Census recorded the parish's population as 2,146.
In scale Deddington is a village, but it has a town centre with a market place and its local football team is called Deddington Town FC.
The name is thought to derive from Daeda, probably an early Anglo-Saxon nobleman, and means "the place of the people of Daeda". The village is believed to have been first settled in the 6th or 7th century AD.
After the Norman conquest of England in 1066, William the Conqueror's step-brother Odo, Bishop of Bayeux, held the manor of Deddington. Odo had Deddington Castle built in what is now the east of the town. The castle was almost completely demolished in the 14th century. There have been two archaeological excavations at the site, in 1947 and in 1978. The remains were reburied once the excavations were complete and only the extensive earthworks are visible today.
