Winkelbury Camp is an Iron Age hillfort, a short distance south-east of the village of Berwick St John, in Wiltshire, England.

A single rampart bank forming a rough oval, 382 by 160 metres (1,253 by 525 ft), encloses an area of about 7.5 hectares (19 acres).

[1] Augustus Pitt Rivers, inheritor of the Rushmore Estate at Tollard Royal, where he was resident from 1880, investigated many prehistoric monuments on Cranborne Chase.

[2] He made a partial excavation of Winkelbury Camp from 1881 to 1882, finding the remains of a timber hut with wattle-and-daub walls; there were flint tools, and pottery from the Romano-British period.

It has been suggested that the purpose of the camp was not just military: it was constructed according to the changing circumstances around the site over time.
