Herschell Carrousel Factory Museum is a historic carousel factory building located at North Tonawanda in Niagara County, New York. The factory complex was constructed between about 1910 and 1915 and consists of six primary structures and five contributory additions. The primary structures are: the Mill Building Carving and Pattern shop (ca. 1910), Paint Shop and Storage Building (ca. 1915), Roundhouse (ca. 1915), Machine Shop (1915), and Assembly and Testing Building (1915). Also on the property is the Number One Special Three Abreast portable carousel, built in 1916.
At one time five carousel builders operated in North Tonawanda. The Allan Herschell Company, and its predecessor the Herschell-Spillman Company, was the most notable of them and operated from 1883 to 1955. The company produced wood carousels into the 1930s.
It was listed on the National Register of Historic Places in 1985 as the Allan Herschell Carousel Factory. Nearby is located the Herschell–Spillman Motor Company Complex, listed on the National Register of Historic Places in 2013.
