Comte Jean de Dunois (Jean d'Orléans) (November 23, 1402 - November 24, 1468) was the bastard of Louis d'Orléans (Duc d'Orléans 1372-1407) and Mariette d'Enghien.

He joined the civil war in France in the time 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. Dunois, together with the legendary Joan of Arc, retook the city of Orléans, and joined her in further victories. They succeed in capturing Reims, which enabled Charles to be crowned as Charles VII of France.
