Sir Edward Ernle, 3rd Baronet (c. 1673 – 1729) of Charborough in Dorset, of Brimslade Park and Etchilhampton, both in Wiltshire, was an English Whig politician who sat in the English and British House of Commons between 1695 and 1729. He had mixed fortunes in finding or holding a seat and often depended on his father-in-law to bring him into his own seat at Wareham when a vacancy arose.
