The Gruber Wagon Works is a historic industrial facility on Red Bridge Road in Bern Township, Pennsylvania, United States. Built about 1882, it is an extremely rare example of a fully outfitted 19th-century wagon manufacturing facility. Originally located in nearby Pleasant Valley, it was moved in 1976 to its present location in Tulpehocken Creek Park to make way for a flood control project. It was designated a National Historic Landmark in 1977. It now serves as part of a county open-air museum.
