Viscount Bolingbroke is a current title in the Peerage of Great Britain created in 1712 for Henry St John. He was simultaneously made Baron St John, of Lydiard Tregoze in the County of Wilts. Since 1751, the titles are merged with the titles of Viscount St John and Baron St John in the same peerage.

Henry St John, 1st Viscount Bolingbroke was an English politician, government official and political philosopher. He was a leader of the Tories, and supported the Church of England politically despite his antireligious views and opposition to theology. He supported the Jacobite rebellion of 1715 which sought to overthrow the new king George I. Escaping to France he became foreign minister for James Francis Edward Stuart. He was attainted for treason, but reversed course and was allowed to return to England in 1723. According to Ruth Mack, "Bolingbroke is best known for his party politics, including the ideological history he disseminated in The Craftsman (1726–1735) by adopting the formerly Whig theory of the Ancient Constitution and giving it new life as an anti-Walpole Tory principle."
