Jean d'Orléans, Count of Dunois (23 November 1402 – 24 November 1468), known as the "Bastard of Orléans" (French: bâtard d'Orléans) or simply Jean de Dunois, was a French military leader during the Hundred Years' War who participated in military campaigns with Joan of Arc.

[1] His nickname, the "Bastard of Orléans", was a mark of his high status, since it acknowledged him as a first cousin to the king and acting head of a cadet branch of the royal family during his half-brother's captivity.

Jean took part in the civil war in France during the reign of Charles VI on the side of the Armagnacs, and was captured by the Burgundians in 1418.

Released in 1420, he entered the service of the Dauphin Charles, fighting in the Hundred Years' War against English forces.

[3] Jean participated in the Praguerie revolt against Charles VII and was a leader of the League of the Public Weal against King Louis XI in 1465, but each time he regained favor at court.
