The Wisconsin Wagon Company Factory is a historic factory building located at 602 Railroad Street in Madison, Wisconsin. The Wisconsin Wagon Company built the factory building in 1903 to construct horse-drawn wagons and carriages. The company transitioned the building to an auto factory in 1917 and continued to use it until 1957. The building is a well-preserved example of a textile mill industrial loft, a popular factory style in many industries around the turn of the century. It was added to the National Register of Historic Places in 2002.
