Rippon Tor is a striking tor on eastern Dartmoor, in England, that stands at 473 metres (1,552 ft) above sea level. It has three cairns, of which are some of Dartmoor's largest, a triangulation pillar, and several rock piles that overlook the northern high moors near and Great Mis Tor. Field boundaries surround the tor. Rippon Tor Rifle Range lies nearby on Horridge Common and the tor is close to the source of the River Ashburn, a tributary of the River Dart.
