Guy III, Count of Saint-Pol

Guy II of Châtillon, Count of Saint-Pol (died 1289) was a French nobleman, and 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 Marie of Hohenstaufen, 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 the Golden Spurs), 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 Mechelen (French: Malines)

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