Raoul de Coucy, Lord of Montmirail

Raoul de Coucy (died c. 1389) was a younger son of Guillaume I de Coucy and Isabelle de Châtillon. His father died in 1335, and Raoul held the lordships of Montmirail, La Ferté-Gaucher and Bailleul.

He married Jeanne d'Harcourt, daughter of the Count of Harcourt and Aumale. Their daughter Blanche carried Montmirail to her husband Hugues II, Count of Roucy, and a younger son, also named Raoul, became bishop of Metz and then of Noyon.
