Maddington is a small settlement and former civil parish on Salisbury Plain in Wiltshire, England. It is on the River Till. Its nearest town is Amesbury, six miles away to the south east.
At the time of the Domesday Book (1086), the manor was held by Amesbury Abbey. In 1825 the parish contained seventy-eight houses and had a population of 369. By 1841 the parish of Maddington extended east and south of the village.
For local government purposes, Maddington was added to the adjoining Shrewton parish in 1934. As Shrewton expanded during the 20th century, Maddington became an area of Shrewton.
