A tor enclosure is a prehistoric monument found in the southwestern part of Great Britain. These monuments emerged around 4000 BCE in the early Neolithic.

Tor enclosures are large enclosures situated near natural rock outcrops, especially tors, on hilltops or the sides of hills. They consist of one or more roughly circular stone walls built around the tor. They are comparable to the causewayed enclosures found elsewhere in the British Isles and many are of similar Neolithic date although others are from later in prehistory.
