Costco Wholesale Corporation (doing business as Costco Wholesale and also known simply as Costco) is an American multinational corporation which operates a chain of membership-only big-box retail stores (warehouse club).[4] As of 2022, Costco is the fifth largest retailer in the world [5] and is the world's largest retailer of choice and prime beef, organic foods, rotisserie chicken, and wine as of 2016.[6] Costco is ranked #11 on the Fortune 500 rankings of the largest United States corporations by total revenue.[7]

Costco's worldwide headquarters are in Issaquah, Washington, an eastern suburb of Seattle, although its Kirkland Signature house label bears the name of its former location in Kirkland. The company opened its first warehouse (the chain's term for its retail outlets) in Seattle in 1983.[8][9] Through mergers, however, Costco's corporate history dates back to 1976, when its former competitor Price Club was founded in San Diego, California.[10][11][12] As of February 2023, Costco has 848 warehouses worldwide:[1] 584 in the United States, 107 in Canada, 40 in Mexico, 31 in Japan, 29 in the United Kingdom, 18 in South Korea, 14 in Taiwan, 14 in Australia, four in Spain, two each in France and China, and one each in Iceland, New Zealand and Sweden.
