General Charles Churchill (2 February 1656 – 29 December 1714) was a British Army officer who served during the War of the Spanish Succession and an English politician who sat in the English and British House of Commons from 1701 to 1710. He was a younger brother of John Churchill, 1st Duke of Marlborough and both his military and political careers were closely connected with his brother's. Along with Marlborough's Irish Chief of Staff William Cadogan, he was one of Churchill's closest advisors. He was a Tory, in contrast to his Whig brother who tolerated and possibly used Churchill's Tory connections.
