Duke of Marlborough ( ) is a title in the Peerage of England. It was created by Queen Anne in 1702 for John Churchill, 1st Earl of Marlborough (1650–1722), the noted military leader. The name of the dukedom refers to Marlborough in Wiltshire. It is one of the few titles in the peerage which allows for suo jure female inheritance, and the only current dukedom to do so.
