The Dukedom of Cleveland was a peerage in the Peerage of England, and later in the Peerage of the United Kingdom, named for Cleveland in northern England. The first creation (along with the Barony of Nunsuch and the Earldom of Southampton) in 1670 was for Barbara Palmer, the mistress of King Charles II, with a special remainder allowing it to be inherited by her illegitimate son by Charles II, Charles Fitzroy (who would not have normally inherited the peerage, being illegitimate). He was made Duke of Southampton, Earl of Chichester, and Baron Newbury in 1675. He inherited the Dukedom of Cleveland in 1709. His son William inherited both Dukedoms, but he had no issue, and since his uncle Henry Fitzroy, 1st Duke of Grafton was not made eligible to inherit the peerage, the title went extinct upon his death.
The Dukedom of Cleveland was created again in 1833 for the third Earl of Darlington, along with the title Baron Raby. He was a great-grandson of Charles, Duke of Cleveland and Southampton, and had been created Marquess of Cleveland in 1827. The title became extinct again in 1891.
