Charles-Philippe d'Orléans (4 April 1905 – 10 March 1970) was a member of the House of Orléans, who bore the courtesy title of Duke of Nemours.

On September 24, 1928, Prince Charles-Philippe d'Orléans married Marguerite Watson (1899-1993), an American whom he had met during a trip to the United States; from their union, which was not recognized by the Duc de Guise (then the Orleanist pretender to the throne of France and head of the family),[2] no children were born.

[4] Prince Charles-Philippe was educated as a child by a tutor who was at one time coveted by the Duchess of Guise for the Count of Paris.

The Count of Paris, Prince Michel's father, disapproved of this union and had forbidden members of his family to attend.

To thank him for this support, Prince Michel asked the Duke of Nemours to be the godfather of his first child, Princess Clotilde (born on December 28, 1968, in Casablanca),[5] and named his first son Charles-Philippe.
