Cullompton is a town and civil parish in the district of Mid Devon and the county of Devon, England, locally known as Cully. It is miles north-north-east of Exeter and lies on the River Culm. In 2010 it had a population of 8,639 and is growing rapidly.
The earliest evidence of occupation is from the Roman period – there was a fort on the hill above the town and occupation in the current town centre. Columtune was mentioned in Alfred the Great's will. In the past the town's economy had a large component of wool and cloth manufacture, then later leather working and paper manufacture.
A large proportion of town's inhabitants are commuters but there is still some local manufacturing, including flour and paper mills. It has a monthly farmers' market held on the second Saturday of every month which is the oldest event of its kind in the South West. It is home to two grade I listed buildings: the fifteenth-century St Andrew's parish church and the seventeenth-century house known as The Walronds. The centre of the town is the only conservation area in Mid Devon and there are seven grade II* listed buildings and ninety grade II listed buildings in the parish.
