Anne de Batarnay de Joyeuse, Baron d'Arques, Vicomte then Duke of Joyeuse (1560 or 1561 – 20 October 1587) was a royal favourite and active participant in the French Wars of Religion.
An intimate friend of Henry III of France, he was known as a minion and keeper of the king's chambers. With these serious responsibilities he also gained a number of privileges around the court, including the wearing of royal colors, and the right to wear jewelry of high majesties of the court, such as a well-known red ruby and diamond ring given to him by the king: it had been confiscated from Princesse Marguerite de Valois as punishment for having accused Anne of trying to interfere with a meeting with the king, as requested of her by Catherine de' Medici. Anne was also a member of the circle of young courtiers known as Les Mignons
