The Robert-Bourassa (formerly known as La Grande-2) is a hydroelectric power plant on the La Grande River that is part of Hydro-Québec's James Bay Project in Canada. The station can generate 5,616 MW and was commissioned in 1979-1981. Together with the adjacent La Grande-2-A generating station, it uses the reservoir and dam system of the Robert-Bourassa Reservoir to generate electricity. It is Canada's largest hydroelectric power station.

Initially known as La Grande-2, it was renamed after Robert Bourassa who, as Premier of Quebec (1970-1976 and 1985-1994) gave the James Bay Project a vital political impetus.
