Duke of Gloucester (/ˈɡlɒstər/ ^ⓘ GLOST-ər) is a British royal title (after Gloucester), often conferred on one of the sons of the reigning monarch. The first four creations were in the Peerage of England and the last in the Peerage of the United Kingdom; the current creation carries with it the subsidiary titles of Earl of Ulster and Baron Culloden.

The title was first conferred on Thomas of Woodstock, the thirteenth child of King Edward III. The title became extinct at his death, as it did upon the death of the duke of the second creation, Humphrey of Lancaster, fourth son of King Henry IV.

The title was next conferred on Richard, brother to King Edward IV. When Richard himself became king, the dukedom merged into the crown. After Richard's death, the title was considered ominous, since the first three such dukes had all died without issue to inherit their titles. The title was not awarded for over 150 years: the next to receive the dukedom was the son of King Charles I, Henry Stuart, upon whose death the title again became extinct.

Prince William, son of the future Queen Anne, was styled "Duke of Gloucester" for his whole life (1689–1700), but was never formally created duke. Frederick, Prince of Wales, was styled "Duke of Gloucester" from 1718–1726, but was then created Duke of Edinburgh rather than of Gloucester.

There was next a creation of a double dukedom (not two dukedoms) for the brother of King George III, Prince William Henry, his proper title becoming "Duke of Gloucester and Edinburgh".

The fifth and most recent creation was for Prince Henry, third son of King George V, styled as His Royal Highness The Duke of Gloucester. Upon Prince Henry's death, the dukedom was inherited by his only surviving son Prince Richard, who still holds the title. The heir-apparent to the title is Alexander Windsor, styled Earl of Ulster. The next in the line of succession is the Earl of Ulster's son Xan Windsor, known by his grandfather's third title of Lord Culloden. The royal dukedom will devolve into an ordinary one when inherited by Alexander Windsor; as a great-grandson of a sovereign he is not entitled to royal style, and will be styled as His Grace The Duke of Gloucester.

Dukes of Gloucester

First creation, 1385–1397

Duke	Portrait	Birth	Marriage(s)	Death
Thomas of Woodstock House of Plantagenet 1385–1397 also: Duke of Aumale (1385–1397), Earl of Essex (1376–1397), Earl of Buckingham (1377)		7 January 1355 Woodstock Palace son of Edward III of England and Queen Philippa	Eleanor de Bohun 1376 5 children	8 September 1397 Calais aged 42

Thomas of Woodstock's son died two years after his father, but never succeeded to his titles except that of Earl of Buckingham. At the time of Thomas's death, he was regarded as a traitor and thus his titles were forfeit after his murder (except Earl of Buckingham). His son had no issue and his male line died out in 1399.

Second creation, 1414–1447

Duke	Portrait	Birth	Marriage(s)	Death
Humphrey of Lancaster House of Lancaster 1414–1447 also: Earl of Pembroke (1414)		3 October 1390 Lancaster Castle son of Henry IV of England and Mary de Bohun	Jacqueline, Countess of Hainaut 1422–1428 (annulled) 1 child (stillborn) Eleanor de Cobham 1428–1441 (annulled) 2 children	23 February 1447 Bury St Edmunds aged 56

Before marrying Humphrey, Eleanor de Cobham was his mistress. At the time of Humphrey's 1447 death, he had two children, Arthur and Antigone. However, both children were born before his marriage to Eleanor and were thus illegitimate and could not succeed to his titles.

Third creation, 1461

Richard succeeded as Richard III in 1483 upon his nephew's disappearance, and his titles merged with the crown.
