Françoise d'Aubigné, Marquise de Maintenon (27 November 1635 – 15 April 1719) was the second wife of King Louis XIV of France.
She was known during her first marriage as Madame Scarron, and subsequently as Madame de Maintenon (UK: , US: , French: [madam d? m?~t(?)n?~] (listen)).
Her marriage to the king was never officially announced or admitted, and thus she was never considered queen of France.
Even so, she was very influential at court, and was one of the king's closest advisers.
She founded the Maison royale de Saint-Louis, a school for girls from poorer noble families, in 1684.
