Hudson Bay (Inuktitut: Kangiqsualuk ilua, French: baie d'Hudson) (sometimes called Hudson's Bay, usually historically) is a large body of saltwater in northeastern Canada with a surface area of 1,230,000 square kilometres (470,000 sq mi).
During his survey of the region, Hudson passed within 100 miles (160 km) of a party led by French explorer Samuel de Champlain, who had ventured south from his base at Quebec, but the two groups were not aware of each other. On his way to Holland, Hudson docked at Dartmouth, England.
