Trevose Head (Cornish: Penn Trenfos, meaning farm of the wall's headland[citation needed]) (grid reference SW853764) is a headland on the Atlantic coast of north Cornwall, on the south-western coast of Great Britain. It is situated approximately 5 miles (8.0 km) west of Padstow. The South West Coast Path runs around the whole promontory and is within the Cornwall Area of Outstanding Natural Beauty and the Trevose Head Heritage Coast. In clear weather, visitors to Trevose Head can see virtually the whole length of the north Cornwall coast; to the north, the view extends beyond the Cornwall county boundary to Hartland Point (40 miles (64 km)), Devon; to the south, it extends beyond St Ives to the headland at Pendeen Watch (35 miles (56 km)).
LB&SCR H2 class 4-4-2 no. 425 (later no. B425, 2425, and 32425) was named Trevose Head after this landmark.
