Niagara Falls is a group of three waterfalls located at the southern end of the Niagara Gorge. The falls span the international border between the Canadian province of Ontario and the U.S. state of New York.
The largest of the three waterfalls is Horseshoe Falls, which straddles the border between Canada and the United States and is also known as the Canadian Falls. The remaining two waterfalls, American Falls and Bridal Veil Falls, are located entirely within the United States.
