Werrington (Cornish: Trewolvredow) is a civil parish and former manor now in Cornwall, England, United Kingdom. Prior to boundary changes it straddled the Tamar and lay within the county of Devon. The portion on the west side was transferred to Cornwall in 1966. It is situated 1 mile (1.6 km) to the west of the Tamar, the traditional boundary between Devon and Cornwall, and 1 mile (1.6 km) north of Launceston.
White's Devonshire Directory (1850) described the parish of Werrington as being near the River Tamar and the Bude Canal and having an area of c. 5,000 acres. Yeolmbridge, Druxton and Eggbeer were then within the parish which was included in Black Torrington Hundred. Druxton Bridge is a Grade II* listed 16th century road bridge.
The descent of the manor of Werrington was as follows:
Before the Norman Conquest of 1066, the manor of Werrington, in the hundred of Black Torrington, was the sole possession of Gytha of Wessex (died 1098 or 1107), the daughter of King Harold (d.1066). In the Domesday Book of 1086 it is recorded as Ulvredintone. Containing 186 households it was far and away the largest settlement in the far west.
