Stowe House in the parish of Kilkhampton in Cornwall, England, UK, was a mansion built in 1679 by John Grenville, 1st Earl of Bath (1628–1701) and demolished in 1739. The Grenville family were for many centuries lords of the manor of Kilkhampton, which they held from the feudal barony of Gloucester, as they did their other principal seat of nearby Bideford in Devon. It is possible that the family's original residence at Kilkhampton was Kilkhampton Castle, of which only the groundworks survive, unusual in that it had a motte with two baileys.

Kilkhampton is a village and civil parish in northeast Cornwall, England, United Kingdom. The village is on the A39 about four miles (6 km) north-northeast of Bude.
