Philippe Charles d'Orléans, petit-fils de France, Duke of Valois (16 July 1664 – 8 December 1666) was a French prince and Grandson of France. He was created Duke of Valois at the time of his birth. He was a short lived nephew of Louis XIV.
He received the names of his father, Philippe and his maternal grandfather, Charles.
Philippe Charles birth helped to smooth over the difficult relationship his parents had; his father was a renowned homosexual who was under the domination of his long term lover the Chevalier de Lorraine. Monsieur complained that Henriette (known simply as Madame) flirted with men at court including the king himself. Court gossip claimed that Philippe Charles' own older sister Marie Louise, was the product of Louis XIV's and Madame's flirting.
