Mayon is a hamlet on the A30 main road north of Sennen in west Cornwall, England. Mayon is about 7 miles (11 km) south-west of Penzance.
Much of the land in St Levan belonged to the manor of Mayon and in the early 17th-century the land was divided between six heiresses, one of whom married John St Aubyn.
