Robert Moses Niagara Power Plant is a hydroelectric power plant in Lewiston, NY near Niagara Falls, New York, United States. The plant diverts water from Niagara River above Niagara Falls and returns the water into the lower portion of the river near Lake Ontario. It utilizes pumped-storage hydroelectricity and has 13 generators at an installed capacity of 2,515 megawatts (MW).

The Robert Moses plant was built to replace power production upon the collapse of the hydroelectric Schoellkopf Power Station on June 7, 1956 in Niagara Falls. It is named after Robert Moses, a mid-20th Century urban planner in New York and is directly opposite of the Sir Adam Beck Hydroelectric Power Stations in Ontario, Canada.
