Sharpham is an historic estate in the parish of Ashprington, Devon. The Georgian mansion house, known as Sharpham House, overlooks the River Dart and is a Grade I listed building. The house was commenced in about 1770 by the Royal Navy captain Philemon Pownoll (d. 1780) to the designs of the architect Sir Robert Taylor (1714–1788). In the opinion of Nikolaus Pevsner it contains "one of the most spectacular and daring later 18th century staircase designs anywhere in England". The park and gardens are Grade II* listed in the National Register of Historic Parks and Gardens.
