Mawnan Smith (Cornish: Mownan an Gov) is a village in the civil parish of Mawnan in south Cornwall, England, United Kingdom.

The village name may derive from the fact that it once had four working smithies serving the many farms in the parish.

It was operated by blacksmith Billy James followed by his son Dryden and closed when the latter died in 1994.

The Mawnan Anvil Trust[4] has since restored the smithy as a working forge with a resident artist blacksmith[5] and the site now also includes a silversmith,[6] sign writer[7] and carpenter.

[8] Mawnan Smith is also home to a number of sightings of the British cryptid, the Owlman.
