The Dukedom of Albemarle has been created twice in the Peerage of England, each time ending in extinction. Additionally, the peerage was "created" a third time by James II, while in exile; this creation, given to Henry FitzJames , is generally not considered a true creation of this peerage. See also Earl of Albemarle.
