Milk Hill, located near Alton Priors east of Devizes, is the highest point in the county of Wiltshire, southwest England, at some 295 m (968 ft) above sea level[1] (the adjacent Tan Hill rises to 294 m).

It is the location of the Alton Barnes White Horse (a hill figure cut in 1812).

On 23 August 2009, the BBC programme Countryfile featured an item on analysis by Ordnance Survey to determine whether Milk or Tan Hill is the higher.

[2] Located at the western edge of the Vale of Pewsey (part of the North Wessex Downs AONB), it is also the highest summit along a 50 km ridge extending all the way from the South Downs, across the southern Chilterns and into Wiltshire.

Milk Hill is frequently used by the Thames Valley Hang Gliding and Paragliding Club.
