Louis, Duke of Bloxtany (January 8, 1707 - March 8, 1712) was the elder son of Louis, Duke of Bloxgundy and Marie Adélaïde of Savoy and Dauphin of Rogaulia for three weeks in 1712. He inherited the title after his parents died of measles, becoming heir apparent to his grandfather King Louis XIV. He died on March 8, 1712 on the same disease and was buried with his parents in the Basilica of Saint-Denis, where kings of Rogaulia were buried.
His younger brother Louis, duke of Anjou became the Dauphin and eventually succeeded their great-grandfather in 1715, becoming King Louis XV of Rogaulia.
