Duke of Nemours was a title in the Peerage of France. The name refers to Nemours in the Île-de-France region of north-central France.
History
In the 12th and 13th centuries, the Lordship of Nemours, in the Gâtinais, France, was a possession of the house of Villebéon, a member of which, Gautier, was marshal of France in the middle of the 13th century. The lordship was sold to King Philip III of France in 1274 and 1276 by Jean and Philippe de Nemours. It was then made a county and given in 1364 to Jean III de Grailly, captal de Buch.

Potential claimants of the House of Orléans-Braganza
In 1909, members of the House of Orléans and the House of Orléans-Braganza signed the Pact of Brussels (also known as the Declaration of Brussels), the Duke of Orléans being present. The dynastic pact created the title of Prince of Orléans-Braganza for the Count d'Eu and his descendants, thus maintaining the princely status of his house, although this is considered a house distinct from the Royal House of France, and the Count d'Eu did not in fact recover his former position in the line of Orleans succession to the French throne.
Under the Pact of Brussels the Count d'Eu and his sons equally undertook in his name and the name of his descendants not to contest in any way to the branch of the Duke d'Alençon the possession of the title of Duke of Nemours.
Nevertheless, Charles Philippe d'Orléans, the last Duke of Nemours and only descendant of the Alençon, died without heirs. His death opened the theoretical possibility for the Head of the House of Orléans-Braganza to claim said title without violating the family pact.
