The eldest surviving son of the Dauphin, he was a fils de France. Louis was born at Versailles to the Duke and Duchess of Burgundy. He was created the Duke of Brittany succeeding his late brother Louis, who was the first to hold the title in 200 years. At the time of his birth, Louis was the third-in-line to the throne, following his father and grandfather Louis, le Grand Dauphin. He was preceded in birth by an elder brother, also named Louis, who was born in 1704 and died in infancy the following year.

Due to the deaths of his grandfather in 1711 and his father in 1712, he was heir apparent to his great-grandfather Louis XIV as Dauphin of France for three weeks in 1712. He was raised under the supervision of the royal governess Louise de Prie. Like his parents, he too died of measles and was buried in the Basilica of St Denis. His younger brother became the Dauphin and eventually succeeded as King Louis XV in 1715.
