St Tudy (Cornish: Eglostudi) is a civil parish and village in north Cornwall, England, United Kingdom. The village is situated in the River Camel valley approximately five miles northeast of Wadebridge.
The village is mentioned as having a cattle fair in Owen's book of fairs 1788.
There was formerly a manor house at Tinten and the chapel may still be recognized. It has been reused as a barn and has a 15th-century window. Other small former manor houses in the parish are Hengar, which was destroyed by a fire in 1904 (in 1906 it was rebuilt in Elizabethan style); Lamellen, Tremeer and Wetherham One of the most well-known of Thomas Rowlandson's paintings is "Hengar House the seat of Matthw Mitchell [sic] Esqr., Cornwall" (1812) which was sold at the Sir Richard Onslow sale, Sotheby's, 15 July 1959. Hengar was a country seat of the Onslows.
The parish church is dedicated to St Tudius and was restored in 1873. There was a Norman church here but the present structure is of the Perpendicular period. There are two aisles the arcades of which are identical. The tower has three stages, is 64 feet high, and is topped with battlements and pinnacles; there are five bells. It is Grade I listed. Anthony Nicholl (died 1658) is commemorated by a sumptuous memorial erected by his wife. In the churchyard is a pre-Norman coped stone with carving, possibly a rare hogback tomb. 
Trevenning cross is at a road junction about one and a half miles northeast of the churchtown. It was found in the hedge close to its present position by J. R. Collins of Bodmin.
Notable people from St Tudy include: William Bligh, naval officer; Eddie George, former governor of the Bank of England; Oscar Kempthorne, statistician and geneticist at Iowa State University; Richard Lower, early experimenter in blood transfusion; Humphrey Nicholls, MP for Bodmin; and Vice Admiral Sir Louis Le Bailly who led a campaign for the local pub to be renamed after William Bligh.
