Ashill is a village and civil parish in the county of Norfolk, situated between Watton and Swaffham.
Ashill was originally called Asleigh, which meant a clearing in the Ash wood. The parish church of St Nicholas dates from the 14th century and stands close to the group of houses that form the oldest part of the village. The village centres on the green and a duck pond. Drovers travelling to Swaffham market would stay overnight on the green, using a shed as accommodation, whilst their cattle grazed on the green and drank from the pond.
