Dauphin of France, originally Dauphin of Viennois, was the title given to the heir apparent to the throne of France from 1350 to 1791, and from 1824 to 1830. The word dauphin is French for dolphin and was the hereditary title of the ruler of the Dauphiné of Viennois. While early heirs were granted these lands to rule, eventually only the title was granted.

Charles V, called the Wise, was King of France from 1364 to his death in 1380. His reign marked an early high point for France during the Hundred Years' War as his armies recovered much of the territory held by the English and successfully reversed the military losses of his predecessors.
