Duke of Kingston-upon-Hull was a title in the Peerage of Great Britain, with the title Earl of Kingston-upon-Hull being a title in the Peerage of England. The Earldom was created on 25 July 1628 for Robert Pierrepont, 1st Viscount Newark. The Dukedom was created on 10 August 1715 for his great-grandson, Evelyn Pierrepont, 1st Marquess of Dorchester, who had succeeded as the fifth Earl of Kingston-upon-Hull in 1690. The Dukedom became extinct on the death of the second Duke in 1773. These titles are often informally shortened to the Duke (or Earl) of Kingston, and should not be confused with the separate Irish title, Earl of Kingston.
