Jaguar Cars Ltd., better known simply as Jaguar is a manufacturer of luxury and executive motor cars, headquartered in Coventry, England, and now operated as part of the Jaguar Land Rover business owned by Tata Motors of India.

Jaguar was founded as the Swallow Sidecar Company by Sir William Lyons in 1922, originally making motorcycle sidecars before switching to passenger cars. The name was changed to Jaguar after World War II due to the unfavourable connotations of the SS initials. Jaguar cars are designed in an engineering centre at their headquarters in Coventry, England and are manufactured in one of three English Jaguar plants; Castle Bromwich in Birmingham, Halewood near Liverpool and Gaydon in Oxfordshire.

Following several subsequent changes of ownership since the 1960s, Jaguar was listed on the London Stock Exchange and became a constituent of the FTSE 100 Index, which ended when Ford acquired Jaguar in 1989. Jaguar also holds Royal Warrants from HM Queen Elizabeth II and HRH Prince Charles.
