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

It existed for the brother of King George III, Prince William Henry; there had been Dukedoms of Gloucester and of Edinburgh but their extinction gave the opportunity for combination.

The dukedom of Gloucester and Edinburgh was a royal dukedom when the duke was entitled to the style "His Royal Highness", as Prince William Henry was, but Prince William Frederick was only granted this style on his marriage in 1816.Royal Styles and Titles – 1816 Royal Warrant.

Dukes 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.
