The American Falls is one of three waterfalls that together are known as Niagara Falls on the Niagara River along the Canada–U.S. border. Unlike the much larger Horseshoe Falls, of which two-thirds of the falls is located in Ontario, Canada, and one-third in the US state of New York, the American Falls is entirely within the United States and New York.
