Penzance (Pensans, : /pɛnˈzæns/) is a town, civil parish, and port in the Penwith district of Cornwall, England, UK.

Granted various Royal Charters from 1512 onwards and incorporated in 1614, it has a population of 20,255 people and is currently Penwith's principal town.

Situated in the shelter of Mount's Bay, the town faces south-east onto the English Channel, is bordered to the west by the fishing port of Newlyn and to the east by the civil parish of Ludgvan. The town's location gives it a temperate climate that makes it warmer than most of the rest of Britain.
