Port Isaac is a small fishing village on the Atlantic coast of north Cornwall, England, in the United Kingdom. The nearest towns are Wadebridge and Camelford, each ten miles away. A nearby hamlet, Port Gaverne, is sometimes considered to be part of Port Isaac. The meaning of the village's Cornish name, Porthysek, is "corn port", indicating a trade in corn from the arable inland district. From 2004 to 2022, the village served as the backdrop to the ITV television series Doc Martin.
