Jeep is an automobile marque (and registered trademark) of DaimlerChrysler. The marque, like all other Chrysler subsidaries, became part of DaimlerChrysler when Daimler-Benz merged with the Chrysler Corporation in 1998. Jeep, like Band-Aid and Xerox, is rapidly becoming a genericized trademark. Unlike Band-Aid and Xerox, however, jeep did not start out as a trademark. The term was first applied to, and continues to be associated with, a military vehicle, the Bantam GP, built by Willys-Overland (and later also by Ford Motor Company) for the United States Army during World War II. The term is also sometimes used to refer generically to what are now known as SUVs, whether the vehicle in question bears the Jeep nameplate or not. The army jeep was one of the vehicles that led to the SUV era of the 1980s.

A division of DaimlerChrysler, the most recent successor company to Willys, now holds trademark status on the word "Jeep" and the distinctive 7-bar front grille design.

The marque has gone through many owners, starting in 1941 with Willys, which produced the first Civilian Jeep (CJ). Willys was sold to Kaiser in 1953, which became Kaiser-Jeep in 1963. American Motors bought the company in 1970. The Chrysler Corporation bought out AMC in 1987, shortly after the Jeep CJ was replaced with the AMC-designed Jeep Wrangler. Finally, Chrysler merged with Daimler-Benz in 1998 to form DaimlerChrysler.

Jeep vehicles are also produced in Beijing, China, by Beijing Jeep Corporation, Ltd., a joint venture between Beijing Automobile Industry Corporation, DaimlerChrysler and DaimlerChrysler China Invest Corporation, established on January 15, 1984.

Jeep vehicles have "model designations" in addition to their common names. Nearly every civilian Jeep has a 'xJ' designation, though not all are as well-known as the classic CJ.
