Duke of Berry or Duchess of Berry was a title in the Peerage of France. The Duchy of Berry, centred on Bourges, was originally created as an appanage for junior members of the French royal family and was frequently granted to female royals. The style Duke of Berry was later granted by several Bourbon monarchs to their grandsons. The last official Duke of Berry was Charles Ferdinand of Artois, son of Charles X. The title Duke of Berry is currently being claimed through its usage as a courtesy title by Prince Alphonse de Bourbon, son of Prince Louis, Duke of Anjou, the Legitimist claimant to the French Throne.
