Jaguar is the luxury vehicle brand of Jaguar Land Rover, a British multinational car manufacturer with its headquarters in Whitley, Coventry, England. Jaguar Cars was the company that was responsible for the production of Jaguar cars until its operations were fully merged with those of Land Rover to form Jaguar Land Rover on 1 January 2013.

Jaguar's business was founded as the Swallow Sidecar Company in 1922, originally making motorcycle sidecars before developing bodies for passenger cars. Under the ownership of SS Cars, the business extended to complete cars made in association with Standard Motor Company, many bearing Jaguar as a model name. The company's name was changed from SS Cars to Jaguar Cars in 1945. A merger with the British Motor Corporation followed in 1966, the resulting enlarged company now being renamed as British Motor Holdings (BMH), which in 1968 merged with Leyland Motor Corporation and became British Leyland, itself to be nationalised in 1975.
