Definition of dauphin
: the eldest son of a king of France
Did You Know?
From 1350 to 1830, dauphin was the title given to the eldest son of a king of France, or the heir apparent to the French crown. The title was established by the royal house of France through the purchase of lands known as the Dauphiné in 1349 by the future Charles V. The Dauphiné was a region and former province in what is now southeastern France. It was sold to King Philip VI of France and ultimately became a grant of land to the eldest son of the French king, who assumed the title (dauphin) attached to the land. The area had a quasi-independent status until it was annexed to France in 1457.
