Knook Castle is the site of an Iron Age univallate hillfort on Knook Down, near the village of Knook in Wiltshire, England, but largely within the civil parish of Upton Lovell. It has also been interpreted as a defensive cattle enclosure associated with nearby Romano-British settlements. It is roughly rectangular in plan with a single entrance on the south/south-east side, but with a later break in the wall on the western side. The site is a scheduled monument.
John Marius Wilson's Imperial Gazetteer of England and Wales described Knook Castle as follows:
