Marie de Nemours, originally known as Marie d'Orléans-Longueville (1625–1707), was the daughter of Henri II d'Orléans, duc de Longueville. After the death of her brother Jean Louis Charles d'Orléans-Longueville in 1694 she succeeded him as sovereign Princess of Neuchâtel, by then the last monarchical state within the Swiss Confederation, although she remained a prominent member of the French royal court.

Descended from Jean d'Orléans, illegitimate son of Louis I, Duke of Orléans, she was known as Mademoiselle de Longueville prior to her marriage. The Dukes of Longueville had acquired the principality of Neuchâtel through marriage to a Swiss princess, Margravine Johanna of Baden-Hochberg-Sausensberg. After the death of her brother Jean-Louis-Charles d'Orléans in 1694 she succeeded him as Princess of Neuchâtel.

By her marriage with Henri of Savoy, she became Duchess of Nemours. The couple were married on 22 May 1657 at Trie. The dukes of Nemours were descendents of the Dukes of Savoy having settled in France in the sixteenth century, where they ranked as princes étrangers.

At an early age she was involved in the first Fronde, of which her father and stepmother, Anne Geneviève de Bourbon, were leaders. She married Henri II, Duke of Nemours in 1657. When he died in 1659, leaving her childless, the rest of her life was mainly spent in contesting her inheritance with her stepmother. Her Savoyard nieces included Marie Jeanne, Duchess of Savoy and Marie Françoise, Queen of Portugal.
