Hudson Bay

Hudson Bay, sometimes called Hudson's Bay, is a large body of saltwater in northeastern Canada with a surface area of 1,230,000 km2. It is located north of Ontario, west of Quebec, north east of Manitoba and southeast of Nunavut, but politically entirely part of Nunavut. Although not geographically apparent, it is for climatic reasons considered to be a marginal sea of the Arctic Ocean. It drains a very large area, about 3,861,400 km2, that includes parts of southeastern Nunavut, Alberta, Saskatchewan, Ontario, Quebec, all of Manitoba, and parts of the U.S. states of North Dakota, South Dakota, Minnesota, and Montana. Hudson Bay's southern arm is called James Bay.

The Eastern Cree name for Hudson and James Bay is Wînipekw or Wînipâkw, meaning muddy or brackish water. Lake Winnipeg is similarly named by the local Cree, as is the location for the city of Winnipeg.
