The Xingó Dam is a concrete face rock-fill dam on the São Francisco River on the border of Alagoas and Sergipe, near Piranhas, Brazil. The dam was built for navigation, water supply and hydroelectric power generation as it supports a 3,162 megawatts (4,240,000 hp) power station. It was constructed between 1987 and 1994 and the last of its generators was commissioned in 1997. In Portuguese, the dam is called the Usina Hidrelétrica de Xingó.
