Duke of Newcastle upon Tyne was a title that was created three times, once in the Peerage of England and twice in the Peerage of Great Britain. The first grant of the title was made in 1665 to William Cavendish, 1st Marquess of Newcastle upon Tyne.[1] He was a prominent Royalist commander during the Civil War.
The related title of Duke of Newcastle-under-Lyne [sic][2] was created once in the Peerage of Great Britain. It was conferred in 1756 on Thomas Pelham-Holles, 1st Duke of Newcastle upon Tyne (of the third creation), to provide a slightly more remote special remainder. The title became extinct in 1988, a year that saw the deaths of the distantly related ninth and tenth Dukes of Newcastle-under-Lyne.

- ^ Despite the name of the town being Newcastle-under-Lyme with an "m", the dukedom was created as Lyne with an "n". There is no known satisfactory explanation for the discrepancy, which may have been an error. If it was an error, however, that error has perpetuated itself in numerous sources, including peerage catalogues.
