Fairfax Assembly & Stamping is a General Motors automobile factory at 3201 Fairfax Trafficway, Kansas City, Kansas in the United States. As of 2022, the 4,900,000 sq ft (460,000 m) plant employs over 2,100 hourly and salaried employees. Employees are represented by United Auto Workers Local 31.

The original Fairfax assembly plant was located next to Fairfax Airport which was the former location of the North American Bomber Production Plant where the B-25 Mitchell was manufactured during World War II. After the war, GM purchased the building and converted it to an automobile assembly plant, and was under the management of GM's newly created Buick-Oldsmobile-Pontiac Assembly Division created in 1945. In 1952, alongside car production, the plant produced F-84F jet-powered fighters.

The original Fairfax plant ceased production in May 1987, and production was moved to Fairfax II. Fairfax II was developed on the former Fairfax airport in a $1 billion project. The new plant began production with the 1988 model Pontiac Grand Prix. In 2003, production of the Chevrolet Malibu was added. On August 23, 2005, the Fairfax facility built its 10 millionth car.

Production of the second generation Buick LaCrosse began at the plant in 2009 and continued through 2016. In January 2013, GM announced $600 million in upgrades to the plant including a new 450,000-square-foot (42,000 m) paint shop and a new stamping press. The renovations were aimed at reducing water consumption and chemical waste, and were not expected to interfere with production. In 2019, the all-new Cadillac XT4 was added.
