Windmill Hill is a chalk hill running alongside the A3(M) in the East Hampshire district of Hampshire, England, overlooking Chalton to the east, and Clanfield to the west. It measures 193 metres above sea level and is named so because of Chalton Windmill which sits upon its summit. This windmill is a Grade II listed building which lay derelict until the late 1970s, when it was restored and converted into a private residence.
