The fur trade is a worldwide industry dealing in the acquisition and sale of animal fur. Since the establishment of world market for in the early modern period furs of boreal, polar and cold temperate mammalian animals have been the most valued. Historically it had a large impact on the exploration and colonization of Siberia, northern North America and the South Shetland and South Sandwich Islands. Today the importance of fur trade has diminished and is currently centered around fur farms and authorized wildlife hunting, but remains controversial due to the cruelty involved and conflicts with the tourism industry. Several animal rights organizations oppose the fur trade, while supporters often cite their methods as not being cruel, that the animal populations are abundant and their rights to practice a traditional lifestyle should be respected. The use of fur on some items today has been partly substituted by synthetic imitations.

Before the colonization of the Americas, Russia was a major supplier of fur-pelts to Western Europe and parts of Asia. Fur was a major Russian export as trade developed in the Early Middle Ages ( 500-1000 AD/CE ), first through the Baltic and Black Seas. The main trading destination was the German city of Leipzig.

Fur is a synonym for hair, used more in reference to non-human animals, usually mammals; particularly those with extensive body hair coverage. The term is sometimes used to refer to the body hair of an animal as a complete coat, also known as the "pelage". Fur is also used to refer to animal pelts which have been processed into leather with the hair still attached. The words fur or furry are also used, more casually, to refer to hair-like growths or formations; particularly when the subject being referred to exhibits a dense coat of fine, soft "hairs".

Animal fur, if layered, rather than grown as a single coat, may consist of short ground hair, long guard hair, and, in some cases, medium awn hair. Mammals with reduced amounts of fur are often called "naked", as in The Naked Ape, naked mole rat, and naked dogs.

An animal with commercially valuable fur is known within the fur industry as a furbearer. The use of fur as clothing and/or decoration is considered controversial by some people: most animal rights advocates object to the trapping and killing of wildlife, and to the confinement and killing of animals on fur farms.

Trade is the transfer of ownership of goods and services from one person or entity to another by getting something in exchange from the buyer. Trade is sometimes loosely called commerce or financial transaction or barter. A network that allows trade is called a market. The original form of trade was barter, the direct exchange of goods and services. Later one side of the barter were the metals, precious metals (poles, coins), bill, paper money. Modern traders instead generally negotiate through a medium of exchange, such as money. As a result, buying can be separated from selling, or earning. The invention of money (and later credit, paper money and non-physical money) greatly simplified and promoted trade. Trade between two traders is called bilateral trade, while trade between more than two traders is called multilateral trade.

Trade exists for man due to specialization and division of labor, most people concentrate on a small aspect of production, trading for other products. Trade exists between regions because different regions have a comparative advantage in the production of some tradable commodity, or because different regions' size allows for the benefits of mass production. As such, trade at market prices between locations benefits both locations.
