Sir Baynham Throckmorton, 3rd Baronet (11 December 1629 – 31 July 1681) of Clearwell, Gloucestershire was an English politician who sat in the House of Commons at various times between 1656 and 1679.
Throckmorton was the son of Sir Baynham Throckmorton, 2nd Baronet (c. 1606–64) and his wife Margaret Hopton, daughter of Robert Hopton.[2]
In 1656, Throckmorton was elected Member of Parliament for Gloucestershire in the Second Protectorate Parliament.[3]
Throckmorton was knighted on 28 May 1660. In June 1660 he was elected MP for Wotton Basset in a by-election to the Convention Parliament.[3] Also in 1660, he was appointed Deputy Constable of St Briavel's, Deputy Warden of the Forest of Dean, Keeper of the Gawle in Dean Forest and Riding Forester and aleconner in Dean Forest. In 1664 succeeded to the baronetcy on the death of his father and was elected MP for Gloucestershire in the Cavalier Parliament in succession to his father. He sat until 1679.[3] He was popular with the Forest of Dean miners, and was elected a "Free Miner" of the Forest of Dean in 1668 and sat as judge of the courts of mine law at Clearwell, his principal manor, in 1668, 1676 and 1680. However, in 1670 there were reports of a violent dispute between Throckmorton and his neighbours.[4]
Throckmorton died at the age of 51.
