Boyertown Auto Body Works was a manufacturer of delivery truck bodies for commercial and industrial use, as well as specialty and military vehicles. The works manufactured electric, gas, and diesel vehicles and bodies on all types of vehicles.

In 1925, Boyertown Auto Body Works was founded by B. Frank Hafer (1883-1968), Dr. W. Howard Swartz (1883-1958), and J. George Hoffman (1902-1957) when they purchased Boyertown Carriage Works from Morris F. Gilbert (1869-1947) and Milton Derr (1864-1926). Boyertown Carriage Works, founded by Jeremiah Sweinhart (1823-1896) in 1872, built horse-drawn carriages. Boyertown Carriage Works changed owners several times.

In 1932, Hafer purchased Swartz's and Hoffman's shares, and his son Paul R. Hafer (1910-2004) became president of the company. Boyertown Auto Body Works contributed to the war effort during World War II, earning an Army-Navy "E" Award.

During the late 1940s, the firm began producing trucks for the television industry and parcel delivery services. Throughout the 1950s and 1960s, they manufactured recreational vehicles, bookmobiles, and ice cream trucks. In 1963, the company introduced a new construction technique, a composite dubbed "Multalloy" used for truck bodies.

Paul R. Hafer retired as company president in 1978. Sales began to decline during the 1980s, and the company went out of business in 1990. Today the same site is now the Boyertown Museum of Historic Vehicles.
