Ottery St Mary, known as "Ottery", is a town in the East Devon district of Devon, England, on the River Otter, about ten miles east of Exeter on the B3174. It is part of a large civil parish of the same name, which also covers the villages of West Hill, Metcombe, Fairmile, Alfington, Tipton St John and Wiggaton. It has a population of 7,692. The place-name 'Ottery St Mary' is first attested in the Domesday Book of 1086, where it appears as 'Otri' and 'Otrei'. 'Oteri Sancte Marie' is first mentioned in 1242. The town takes its name from the river Otter on which it stands, the river taking its name from the animal. The 'St Mary' element refers to the fact that the town belonged to the church of St Mary in Rouen in 1086.
