Porthleven is a town, civil parish and fishing port near Helston in Cornwall, England. It is the most southerly port on the island of Great Britain, and was originally developed as a harbour of refuge, when this part of the Cornish coastline was recognised as a black spot for wrecks in days of sail. Nearby Loe Bar was particularly infamous, with swimmers and surfers being warned off the area to this day.
Historically and for local government purposes, Porthleven was included within the town boundaries of nearby Helston from 1934 until 1974 or later. Prior to 1934 it was part of the civil parish of Sithney. After years of growth, it now has its own town council. Its population recorded by the United Kingdom Census 2001 was 3,190.
