Jacques de Châtillon (died 11 July 1302) was Seigneur de Leuze, de Condé, de Carency, de Huquoy et d'Aubigny, the son of Guy III, Count of Saint-Pol and Matilda of Brabant. King Philip IV of France succeeded in his attempt to annex the County of Flanders by appointing Jacques, the uncle to his wife Joan I of Navarre, as governor of the County in 1300. The Flemish Count Guy of Dampierre and his two sons had been taken captive by the French.
