Mary Scott, Countess of Deloraine (née Howard, later Windham; bap. 28 February 1703 – 12 November 1744), was a British courtier and royal governess. A member of the Howard family, her tenure at court began with an appointment as a maid of honour to the future Queen Caroline; she later served as governess to Caroline's daughters Mary and Louise. In 1737, she became a royal mistress of the widowed King George II. Her role ended in 1742 after Mary, possibly drunk, knocked him out of a chair during a party.
