John Pocklington (1658–1731) was an English lawyer and Whig politician who sat in the English and British House of Commons between 1695 and 1713. He was appointed a Welsh circuit judge in 1707 and a judge of the Court of Exchequer (Ireland) in 1714, as a result of which he settled in Ireland. He suffered from chronic ill health, and was imprisoned on the orders of the Irish House of Lords in 1719, during a major Constitutional crisis. His descendants, who adopted the surname Domvile, were wealthy landowners in south County Dublin.
