Cotehele, ( Cornish: Koesheyl) ( grid reference SX422685 ), is a mediaeval/ Tudor house located in the parish of Calstock, Cornwall, England, UK. In Cornish the placename is Koesheyl (the creek in the wood perhaps). Probably originating circa 1300. The main phases of building appear to have been by Sir Richard Edgcumbe from 1485-89 and his son, Sir Piers Edgcumbe, from 1489-1520. This house is one of the least altered of the Tudor houses in the United Kingdom. The outbuildings include a stone dovecote in a remarkable state of preservation. For centuries a home of the Edgcumbe family, the house and estate are now under the care of the National Trust. The grounds stretch down to a quay on the River Tamar where there is an outpost of the National Maritime Museum. The gardens and parkland are listed as Grade II* on the Register of Parks and Gardens of Special Historic Interest in England
- Cotehele was used in the filming of Trevor Nunn's 1996 film adaptation of Twelfth Night .
