Hudson Bay is a large (1.23 million km²), relatively shallow body of water in northeastern Canada. It is approximately 850 miles long and 650 miles wide. It drains a very large area that includes parts of Ontario, Quebec, Saskatchewan, Alberta, most of Manitoba, parts of North Dakota, South Dakota, Minnesota, and Montana, and the southeastern area of Nunavut. A smaller offshoot of the bay, James Bay, lies to the south. The International Hydrographic Organization lists Hudson Bay as part of the Arctic Ocean. On the east it is connected with the Atlantic Ocean by Hudson Strait, and on the north with the rest of the Arctic Ocean by Foxe Basin (which is not considered part of the bay) and Fury and Hecla Strait. Geographic coordinates: 78° to 95° W, 51° to 70° N.
The Eastern Cree name for Hudson and James Bay is Wînipekw (Southern dialect) or Wînipâkw (Northern dialect), meaning muddy or brackish water. Lake Winnipeg is similarly named by the local Cree, as is the location for the City of Winnipeg.
