Duke of Hereford

Duke of Hereford was a title in the Peerage of England. It was created in 1397 for Richard II's cousin, Henry Bolingbroke, due to his support for the King in his struggle against their uncle Thomas of Woodstock, 1st Duke of Gloucester. It merged in the crown on Henry's usurpation two years later, and has never since been recreated.

The title takes its name from Hereford, Herefordshire, England. The city lies near the border with Wales, and has more often been in the title of the Earl of Hereford or the Viscount Hereford.
