The Hudson's Bay Company is a Canadian retail business group. A fur trading business for much of its existence, it became the largest and oldest corporation in Canada, and now owns and operates retail stores across the country. The company's namesake business division is Hudson's Bay, commonly referred to as The Bay.

The fur trade is a worldwide industry dealing in the acquisition and sale of animal fur. Since the establishment of a world fur market in the early modern period, furs of boreal, polar and cold temperate mammalian animals have been the most valued. Historically the trade stimulated the exploration and colonization of Siberia, northern North America, and the South Shetland and South Sandwich Islands.
