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 wider Horseshoe Falls, which is on the Canadian side of the border, the American Falls is completely within the U.S. state of New York.

The falls receive approximately 10% of the flow from Niagara River, with most of the rest going over Horseshoe Falls, from which it is separated by Goat Island. It has a straight line crest width of about 253 m (830 feet). If measured along the jagged lip of the falls, the crest is about 290 m (950 feet) long. The torrent of water passing over the crest of the falls is about 0.6 m (2 feet) deep.

The height of the American Falls ranges between 21 to 34 metres (70-110 feet). This measurement is taken from the top of the Falls to top of the rock pile. The height of the Falls from the top of the Falls to the river is 57 metres (188 feet).

The falls are viewable from a steep angle on the American side, where it is possible to approach to within several meters of the edge of the falls. One can view the falls from the bank of the river, as well as on Goat Island, which is accessible by a pedestrian bridge that crosses the rapids of the Niagara river upstream from the falls. The falls are viewable head-on from the Canadian side in Niagara Falls, Ontario.
