Chapel Carn Brea

Chapel Carn Brea is an elevated Hercynian granite outcrop, owned by the National Trust at the southern edge of the civil parish of St Just, Cornwall, England, United Kingdom. The hill is 5 kilometres south of St Just and 3.5 kilometres east of Sennen Cove, and just to the north of the A30 London to Land's End road, which runs through the village of Crows-an-Wra. It should not be confused with another Carn Brea, the hill overlooking the Camborne–Redruth area.

Chapel Carn Brea is often described as the first hill in Cornwall and rises 198 metres above sea level.
