Castle Hill is the site of an Iron Age univailate hillfort located in the civil parish of Burley in the New Forest national park in Hampshire, England. Its single rampart and ditch earthworks enclose approximately five acres of land and is in reasonable condition for the most part, although it is cut through by tracks leading to local houses. Parts of the interior are marshy and much of it is overgrown with oak, silver birch, holly and bracken. The bank is at its highest on the eastern side, as the west side slopes steeply away. Hampshire treasures lists the site as a Scheduled Ancient Monument (No. 226).
