Duke of Gloucester and Edinburgh /ˈɡlɒstə/ was a British royal title (after Gloucester and Edinburgh) in the Peerage of Great Britain; the sole creation carried with it the subsidiary title of Earl of Connaught.

The only creation was for the brother of King George III, Prince William; there had previously been Dukes of Gloucester and of Edinburgh, but Prince William's full title was "Duke of Gloucester and Edinburgh".

After the Union of Great Britain, the Hanoverian kings liked to grant double titles (one from one constituent country, one from another) to emphasise unity.
