哈得逊海峡（Hudson Strait）是加拿大北部一海峡，将巴芬岛同拉布拉多半岛分割开来。哈得逊海峡东为拉布拉多海，西为福克斯湾和哈得逊湾。

该海峡得名于英国探险家亨利·哈得逊。

Hudson Strait links the Atlantic Ocean to Hudson Bay in Canada. This strait lies between Baffin Island and the northern coast of Quebec, with its eastern entrance marked by Cape Chidley in Quebec and Resolution Island off Baffin Island. The strait is about 450 mi (720 km) long. Its width varies from 150 mi (240 km) at its largest point, to a minimum of 40 mi (64 km).
