Marie-Adélaïde of Savoy (December 6,1685-February 12,1712) was the mother of King Louis XV of France. She married Louis, Duke of Burgundy, grandson of Louis XIV in 1696. She was well liked by the Sun King and became Dauphine after the death of her father-in-law, the Grand Dauphin. Both she and her husband fell ill in early 1712 and died within six days of each other. Her second son died the same year.

They had three children:

• • Louis, Duke of Brittany (1704-1705)
  • Louis, Duke of Brittany (1707-1712)
  • Louis XV of France (1710-1774)
