Charles Dunster (1750–1816) was a British writer, and translator. 
He was the only son of the Rev. Charles Dunster, prebendary of Salisbury. He was admitted at Oriel College, Oxford, as a commoner in 1767, took his B.A. degree at the end of 1770, migrated early in 1771 to Balliol, and again in 1773 to Trinity.
He was instituted to the Worcestershire rectories of Oddingley and Naunton Beauchamp in 1776, and in 1789 (Arnold, Petworth) to that of Petworth in Sussex. He became rural dean of West Sussex, and held the rectory of Petworth till his death in April 1816.
