Neoplan Bus GmbH is a German automotive company that manufactures buses, trolleybuses and coaches. In 2001, it became a subsidiary of MAN Truck & Bus SE.

Founded in Stuttgart in 1935 by Gottlob Auwärter (1903-1993), the company produced bodies for bus and truck chassis. By 1953, the company had moved away from producing buses on truck chassis and switched to a partial monocoque design with a steel tube skeleton providing structural support, reinforced by welded side panels. The engine was moved to the rear. Air suspension became available in 1957.

In 1964, the founder's second son Konrad Auwärter developed a double-decker bus design for a service bus as part of his dissertation. 
The ‘Do-Bus’ design had a low weight and could carry more than 100 passengers. It also had a low-frame front axle and forward-mounted steering that allowed for a low, flat floor. The double-deck principle was applied to the coach design, creating a comfortable, high-capacity touring vehicle. This vehicle was known as the Skyliner.
