Coney's Castle is an Iron Age hillfort in Dorset, England. The name Coney is from the Old English for rabbit (Latin cuniculus), suggesting medieval use as a domestic warren, as at nearby Pilsdon Pen. The fort is on a narrow north–south ridge reaching a height of 210 m, with linear ramparts across the ridge, steep natural slopes to the west and a high artificial rampart with ditch to the east. A small lane runs along the ridge, bisecting the hillfort. The lane is also part of the Wessex Ridgeway long-distance trail. There is a convenient car park next to the north rampart. The remains of the hillfort are designated as a scheduled monument and was on the Heritage at Risk Register but was removed in 2022 as a result of the Hillforts and Habitats Project. The site is looked after by the National Trust as is Lambert's Castle about 1.5 km to the north.
