Dungeon Hill is an Iron Age hillfort, about 1+1⁄4 miles (2 kilometres) north of the village of Buckland Newton in Dorset, England.

[2] The fort is on a low hill, height 600 feet (180 m); it has a single bank in a roughly oval shape, enclosing an area of about 9 acres (3.6 hectares).

There are traces af an outer bank on the east side.

[2][3][4] On the east facing slope of the hill there are four lynchets, suggesting cultivation in the medieval period.

[2][4] In the late 18th century Fitzwalter Foy, resident of nearby Duntish Court,[5] who was the owner of the fort, cleared the site of woodland, and he recovered human bones, sword blades, Roman coins and other finds.
