The Hudson Bay expedition of 1686 was one of the Anglo-French conflicts on Hudson Bay. It was the first of several expeditions sent from New France against the trading outposts of the Hudson's Bay Company in the southern reaches of Hudson Bay. Led by the Chevalier de Troyes, the expedition captured the outposts at Moose Factory, Rupert House, Fort Albany, and the company ship Craven.

Although France and England were then at peace, war broke out between them in 1689, and the conflict over the Hudson Bay outposts continued. One of Troyes' lieutenants, Pierre Le Moyne d'Iberville, made further expeditions against HBC holdings; these culminated in the French victory at the 1697 naval Battle of Hudson's Bay. At the end of the war, the French controlled all but one of the company's outposts.
