Maiden Newton is a village and civil parish in the county of Dorset in south-west England. It lies within the West Dorset administrative district, about 9 miles (14 km) north-west of the county town Dorchester. It is sited on Upper Greensand at the confluence of the River Frome with its tributary of equivalent size, the Hooke. Both these rivers have cut valleys into the surrounding chalk hills of the Dorset Downs. Maiden Newton railway station, which serves the village, is situated on the Heart of Wessex Line. The A356 main road also passes through the village. In the 2011 census the parish—which does not include the adjacent settlements of Frome Vauchurch and Tollerford— had a population of 1,119.
