Charlton Down is a new village in Dorset, England, situated approximately 4 miles (6.4 km) north of the county town Dorchester.

The village of Charlton Down developed from the site of the old Dorset County Asylum.

[2] The hospital closed in 1992 and three of the larger buildings — Redwood (built in 1863), Greenwood (1896) and Herrison House (1904) — have been converted into apartments.

The original cricket ground has a new pavilion and there is a thriving cricket club in the summer[3] with one large and one small park serving to the village [4][5] the village has a shop which contains a post office [6] and a cash dispensary.

The new name of Charlton Down was chosen to honour a medieval epithet for the hill on which it was built.
