AM General is an American heavy vehicle and contract automotive manufacturer based in South Bend, Indiana. It is best known for the civilian Hummer and the military Humvee that are assembled in Mishawaka, Indiana. From 1974 through 1979, the company also manufactured transit buses, making more than 5,400 of them.

AM General has also been a provider of vehicles for the CUCV program carried out by the United States Armed Forces.

AM General traces its roots to the Standard Wheel Company of Terre Haute, Indiana, which expanded in 1903 to include the Overland Automotive Division. In 1908, John North Willys purchased the Overland company, then based in Indianapolis, Indiana, and renamed it Willys-Overland Motors. In 1941, the U.S. Army awarded a contract to Willys-Overland Motor Company to produce the Willys MB, also known as the Jeep, for the U.S. Infantry. It then mass-produced that vehicle as "America's first four-wheel-drive, one-fourth-ton, tactical utility truck"—the Jeep of World War II fame.

In 1953, Kaiser Motors purchased Willys-Overland, changing its name first to Kaiser-Willys Motor Company, and in 1963, to Kaiser-Jeep Corporation. In 1970, it was purchased by American Motors Corporation (AMC). In July 2020, KPS Capital Partners acquired the company.

In 1964, Kaiser-Jeep purchased the Studebaker facilities on Chippewa Avenue in South Bend, Indiana, Studebaker's "General Products Division", and its substantial defense contracts.

At the time, Kaiser had been awarded a US$87 million Army truck contract, and under government pressure, agreed to perform the work at the South Bend plant it had recently acquired from Studebaker.

In 1970, American Motors Corporation (AMC) purchased the Jeep Corporation from Kaiser, when Kaiser decided to leave the auto business.

In 1971, AMC made the General Products Division of Jeep (producing military trucks as well as contract and non-commercial vehicles) a wholly owned subsidiary and renamed it "AM General Corporation".
