SS Baychimo was a steel-hulled 1,322 ton cargo steamer built in 1914 in Sweden and owned by the Hudson's Bay Company, used to trade provisions for pelts in Inuit settlements along the Victoria Island coast of the Northwest Territories of Canada.

After World War I she was passed to the United Kingdom as part of the reparations by Germany for shipping losses and acquired by the Hudson's Bay Company in 1921.

Renamed Baychimo and based in Ardrossan, Scotland, she completed nine successful voyages along the north coast of Canada, visiting trading posts and collecting pelts.

On November 24, a powerful blizzard struck, and after it abated there was no sign of Baychimo; the skipper concluded that she must have broken up and sunk in the storm.
