Port Gaverne (thought to have come from ‘Karn Hun’, which in the dialect of Cornish local to the area means ‘rocky haven‘), is a hamlet on the north coast of Cornwall, England, UK, about 0.5 miles (0.80 km) east of Port Isaac and part of St Endellion parish.

Historically, Port Gaverne existed as a port for sand and slate from the local mine, and for the local fishing catch, particularly pilchards, and has little recorded history prior to the 19th Century, when economic activity at the port was at its peak. In the 20th Century these industries declined as railways supplanted transport by sea.

The appearance of the hamlet has changed little in two centuries, with its stone and slate buildings recognised for their character and the rugged local coastline as a heritage coast. Nowadays the settlement relies almost entirely upon tourism.
