Duke of Edinburgh, named after the city of Edinburgh, Scotland, is a title that has been created four times for members of the British royal family since 1726. The current holder is the Prince Philip, consort to Queen Elizabeth II.

The title was first created in the Peerage of Great Britain on 26 July 1726 by George I, who bestowed it on his grandson Prince Frederick, who also became Prince of Wales the following year. The subsidiary titles of the dukedom were Baron of Snowdon, in the County of Caernarvon, Viscount of Launceston, in the County of Cornwall, Earl of Eltham, in the County of Kent, and Marquess of the Isle of Ely. These titles were also in the Peerage of Great Britain. The marquessate was apparently erroneously gazetted as Marquess of the Isle of Wight although Marquess of the Isle of Ely was the intended title. In later editions of the London Gazette the Duke is referred to as the Marquess of the Isle of Ely. Upon Frederick's death, the titles were inherited by his son Prince George. When Prince George became King George III in 1760, the titles "merged into the Crown", and ceased to exist.

On 19 November 1764, George III created a variation of the title for his younger brother, Prince William, the full form being "Duke of Gloucester and Edinburgh". This title was in the Peerage of Great Britain and the sole subsidiary title of the dukedom was Earl of Connaught, in the Kingdom of Ireland, a title in the Peerage of Ireland. In 1805, the titles were inherited by William's only son, another William, who died without a male heir, causing the title to cease to exist.
