Quarley Hill is the site of an Iron Age univallate hill fort in Hampshire, southern England. The hill affords commanding views of the surrounding countryside. Oval in plan, the fort is in good condition with a counter-scarp and well defined entrances at north-east and south-west. It is built on the site of an earlier palisade enclosure. There is evidence of prehistoric activity in the area including four large Bronze Age ditches radiating from the hill fort, believed to be part of a Bronze Age farming settlement, and a barrow cemetery about a mile away to the north. There is also evidence for a Roman settlement on the northeast side of the hill, with Roman coins of Maximum II and Constantine the Great, and other sherds found in 1951.
