John Wharton (born John Hall-Stevenson) (21 June 1765 – 29 May 1843) was a British landowner and MP. He was born the eldest son of Joseph William Hall-Stevenson of Skelton, in the North Riding of Yorkshire and educated at the Royal School, Armagh, Trinity College, Dublin and Lincoln's Inn. He succeeded his father in 1786, inheriting the ruinous Skelton Castle. He served as the Whig MP for Beverley from 1790 to 1796 and again from 1802 to 1826. By 1829 he was in debt and spent the next 14 years in the Fleet Debtors Prison, where he died childless in 1843.
