The White Motor Company was an automobile, truck, bus, and agricultural tractor manufacturer from 1900 until 1980. It was founded in Cleveland, Ohio, by Rollin Henry White (1872-1962) as a spinoff from his father's sewing machine company, after White became interested in steam engines for early automobiles and trucks. The company produced steam cars until 1911, when it transitioned to gasoline-powered vehicles. Following World War I, production shifted to focus on trucks; buses were added in 1936, including a line of touring buses designed to transport visitors through U.S. National Parks. The company became a military supplier during World War II, but entered a phase of decline afterwards. It filed for bankruptcy in 1980, with Volvo acquiring the bulk of its assets.

The company's White Diesel Engine Division in Springfield, Ohio, manufactured diesel engine generators, which powered U.S. military equipment and infrastructure, including Army Nike and Air Force Bomarc launch complexes, as well as other guided missile installations and proving grounds, sections of SAGE and DEW Line stations, radars, Combat Direction Centers, and other ground facilities of the U.S. aerospace defense ring.
