Jean de Châtillon (1283–1363), second son of Gaucher V de Châtillon, Constable of France, and Isabeau de Dreux, was lord of Châtillon-sur-Marne and Gandelu, and held La Ferté-en-Ponthieu through his wife Éléonore de Roye. As grand queux of France he served Philip the Fair, who named him an executor of his will in 1314.

When war with England came, he went to Flanders with John, Duke of Normandy, in 1340 and defended Tournai against the English siege in 1341. Appointed grand maître de France in 1350, he was present at Poitiers in 1356. He died in 1363, very old, and was buried at Cerfroy near Gandelu.
