Trevowhan is a hamlet[1] in the parish of Morvah, Cornwall, England, UK, and lies 0.5 miles east of the village of Morvah.
A terrace of a house and two cottages in the hamlet is a Grade II listed building.
In 1427 dwelling houses and surrounding land there was recorded as being held by a John Trevaygnon, but it was not known which Lord he was in the service of. In 1882 there were two farms there consisting of 82.5 acres.[2]
On 10 July 1745 John Wesley visited the hamlet and preached a sermon, during which a constable read the Riot Act.[3]
Trevowhan has a bus service which is used by visitors to nearby Chun Quoit.[4]
