The Buffalo History Museum (previously known as the Buffalo and Erie County Historical Society) is in the city of Buffalo, New York, United States. It occupies the building constructed in 1901 as the New York State pavilion for that year's Pan American Exposition. It is the sole surviving permanent structure from the exposition. As planned, the (then) Buffalo Historical Society moved into the building after the exposition.
