Philip of Orléans (1 July 1336 – 1 September 1375) was a Duke of Orléans, Touraine, and Count of Valois, the fifth son of King Philip VI of France[1] and his wife Joan the Lame.

His father named him Duke of Orléans, a newly created duchy, in 1344.

On 8 January 1345, Philip married his second-cousin, Blanche of France (1 April 1328 – 1392), the daughter of King Charles IV of France and Joan of Évreux,[1][2] but they had no children.

He also had a natural daughter, Marie d'Orléans, who married Gédéon V of Beauvilliers.

As a consequence of the Treaty of Brétigny, he served some time as a hostage in England for the good behavior of his brother King John II of France, when he was temporarily released.
