Piran or Pyran, died c. 480, was a 5th-century Cornish abbot and saint, possibly of Irish origin. He is the patron saint of tin-miners, and is also generally regarded as the patron saint of Cornwall, although Michael and Petroc also have some claim to this title.

Cornwall is a ceremonial county in South West England. It is recognised by Cornish and Celtic political groups as one of the Celtic nations, and is the homeland of the Cornish people. The county is bordered by the Atlantic Ocean to the north and west, Devon to the east, and the English Channel to the south. The largest settlement is Falmouth, and the county town is the city of Truro.
