Charles James Spencer-Churchill, 12th Duke of Marlborough (born 24 November 1955), styled Earl of Sunderland until March 1972 and Marquess of Blandford until October 2014, and often known as Jamie Blandford or Jamie Marlborough, is a British peer and the current Duke of Marlborough.
He is the eldest surviving son of the 11th Duke of Marlborough and his first wife, Susan Mary Hornby. As a member of the Spencer family, he is a relative of the war-time Conservative Prime Minister Sir Winston Churchill (his first-cousin, three times removed) and of Diana, Princess of Wales, born Lady Diana Spencer. He is also a descendant of the prominent American Vanderbilt family through his great-grandmother Consuelo Vanderbilt.
