The Yellow Coach Manufacturing Company (informally Yellow Coach) was an early manufacturer of passenger buses in the United States. Between 1923 and 1943, Yellow Coach built transit buses, electric-powered trolley buses, and parlor coaches. Founded in Chicago in 1923 by John D. Hertz as a subsidiary of his Yellow Cab Company, the company was renamed "Yellow Truck and Coach Manufacturing Company" in 1925 when General Motors (GM) purchased a majority stake. After GM completely acquired the company in 1943, it was merged with GM's truck division to form the GM Truck & Coach Division.
