Is Niagara Falls in the United States? It Straddles the Border

Niagara Falls comprises three waterfalls on the Niagara River, which forms the international boundary:

• Horseshoe Falls – mostly in Ontario, Canada.
• American Falls & Bridal Veil Falls – in New York, USA.

So the falls are shared; neither country owns them entirely. The Rainbow Bridge, Whirlpool Bridge, and Lewiston–Queenston Bridge connect the two nations nearby.
