Noss Mayo is a village in the civil parish of Newton and Noss in the South Hams district of south-west Devon, England, about 6 miles south-east of Plymouth. It lies about a mile inland, on the southern bank of Newton Creek, an arm of the estuary of the River Yealm. On the opposite, northern bank of the creek is Newton Ferrers, a slightly larger settlement. The two villages are said to be among the most attractive and un-spoilt villages in Devon.
