Guy III, Count of Saint-Pol

Guy II of Châtillon, Count of Saint-Pol (d. 1289), French nobleman, was a younger son of Hugh I of Châtillon and Marie of Avesnes.

While his elder brother John I of Châtillon succeeded to their mother's County of Blois, Guy was given their father's county of Saint-Pol-sur-Ternoise at his death in 1248.

On January 16, 1255, he married Matilda of Brabant (d. 1288), daughter of Henry II, Duke of Brabant, and thereafter was a supporter of his brother-in-law Henry III against Guelders. They had six children:

• Hugh II of Châtillon (d. 1307), Count of Saint Pol and later Count of Blois
• Guy III of Châtillon (d. 1317), Count of Saint Pol
• Jacques I of Leuze-Châtillon (d. 1302, Battle of Courtrai), first of the lords of Leuze, married Catherine de Condé and had issue; his descendants brought Condé, Carency, etc. into the House of Bourbon.
• Beatrix (d. 1304), married John I of Brienne, Count of Eu
• Jeanne, married Guillaume III de Chauvigny, Lord of Châteauroux
• Gertrude, married Florent, Lord of Malines

A faithful vassal of France, he joined the Eighth Crusade (1270) and the ill-fated Crusade of Aragón of Philip the Bold.
