The medieval Knepp Castle (sometimes referred to as 'Old Knepp Castle', to distinguish it from the nearby 19th-century mansion) is to the west of the village of West Grinstead, West Sussex, England near the River Adur and the A24 (grid reference TQ163209). The castle was probably founded by the Braose family in the 12th century. King John confiscated the castle along with the Braose lands in 1208. Knepp was used as a hunting lodge, and John visited the castle several times. He ordered its destruction in both 1215 and 1216 during the First Barons' War.

Knepp Castle continued to be used into the 14th century and hosted reigning monarchs on several occasions. The castle eventually fell out of use, and by the early 18th century was mostly destroyed. Later that century, stone from the castle was used to build a nearby road. The land around the castle is now the site of Knepp Wildland.
