Leather is a durable and flexible material created by tanning animal rawhide and skins. The most common raw material is cattle hide. It can be produced at manufacturing scales ranging from artisan to modern industrial scale. Leather making has been practiced for more than 7,000 years;^[1] the earliest record of leather artifacts dates back to 2200 BCE.

Leather is used to make a variety of articles, including footwear, automobile seats, clothing, bags, book bindings, fashion accessories, and furniture. It is produced in a wide variety of types and styles and decorated by a wide range of techniques.

Leather usage has come under criticism in the 20th and 21st centuries by animal rights groups. These groups claim that buying or wearing leather is unethical because producing leather requires animals to be killed. However, according to the LCA report for the United Nations Industrial Development Organization, 99% of the raw hides and skins used in the production of leather derive from animals raised for meat and/or dairy production.
