John of Orléans, Count of Dunois (French Jean d'Orléans, comte de Dunois, also known as John of Orléans and Bastard of Orléans) (23 November 1402 – 24 November 1468) was the illegitimate son of Louis d'Orléans (Duc d'Orléans 1372-1407) by Mariette d'Enghien. The term "Bastard of Orléans" (bâtard d'Orléans) was the usual name for most of his career. In his era this was a term of respect 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.
