Dartmoor is an area of moorland in south Devon, England. Protected by National Park status, it covers 954 square kilometres (368 sq mi).

The granite upland dates from the Carboniferous period of geological history. The moorland is capped with many exposed granite hilltops known as tors, providing habitats for Dartmoor wildlife. The highest point is High Willhays, 621 m (2,037 ft) above sea level. The entire area is rich in antiquities and archaeology.

Dartmoor is managed by the Dartmoor National Park Authority whose 22 members are drawn from Devon County Council, local district councils and Government.

Parts of Dartmoor have been used as military firing ranges for over 200 years. The public enjoy extensive access rights to Dartmoor (including restricted access to the firing ranges) and it is a popular tourist destination. The organisation responsible for tourism on Dartmoor is the Dartmoor Partnership.

Dartmoor includes the largest area of granite in Britain, with about 625 square kilometres (241 sq mi) at the surface, though most of it is under superficial peat deposits. The granite (or more accurately adamellite) was intruded at depth as a pluton into the surrounding sedimentary rocks during the Carboniferous period, probably about 309 million years ago. It is generally accepted that the present surface is not far below the original top of the pluton; evidence for this includes partly digested shale xenoliths, contamination of the granite and the existence of two patches of altered sedimentary rock on top of the granite. A considerable gravity anomaly is associated with the Dartmoor pluton as with other such plutons.^{[citation needed]} Measurement of the anomaly has helped to determine the likely shape and extent of the rock mass at depth.
