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 styled 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.
After the death of the Queen mother, Anne of Austria in January 1666, Louis XIV promised to raise Philippe Charles with his first cousin le Grand Dauphin. At the end of the year, Philippe Charles himself succumbed and died at the Palais Royal in Paris, the grace and favour residence of his parents. He was buried at the Royal Basilica of Saint Denis, outside Paris.
