Thorncombe Beacon is a hill between Bridport and Charmouth in Dorset, England.

It is 157 metres (515 ft) high, compared to 191 metres (627 ft) for Golden Cap which lies about 3 kilometres (1.9 mi) to the west.

It forms part of the Jurassic Coast, a World Heritage Site and the South West Coast Path and the Monarch's Way skirt the hilltop.

Three bowl barrows to the north-east of the summit constitute a scheduled monument.
