William II, Marquis of Namur (22 January 1355 – 10 January 1418) inherited the Marquisate of Namur from his father William I in 1391 and held it until his own death. His mother was Catherine of Savoy († 1388), daughter of Louis II of Savoy, baron of Vaud, and Isabella of Châlon.
Reign
His rule as marquis of Namur was a peaceful one in which he devoted himself to encouraging commerce, industry, and the building of fortifications. He did participate in 1408 in the suppression of a revolt by the people of Liège, together with John the Fearless, Duke of Burgundy, William IV, Count of Hainaut and Louis VII, Duke of Bavaria.
Marriages
His first wife was Marie de Bar, daughter of Robert I, Duke of Bar and Marie of France, Duchess of Bar.
In 1393, he remarried Jeanne d'Harcourt (1372–1456), daughter of John VI, Count of Harcourt and Catherine of Bourbon.
He had no surviving children, and so on his death, William II was succeeded as Marquis by his brother John III.
