Albert, Lake, or Albert Nyanza, a lake in the Great Rift Valley of eastern Africa. The lake is divided between Uganda on the east and the Democratic Republic of the Congo on the west. The lake has an area of 2,075 square miles (5,374 km2) and a maximum depth of 170 feet (52 m). It is about 110 miles (180 km) long, northeast-southwest, and up to 30 miles (48 km) wide. The lake receives the waters of the Semliki River, which drains Lake Edward to the southwest, and the Victoria Nile, flowing from Lake Victoria to the southeast. Lake Albert discharges its waters through the Albert Nile, called the White Nile after it enters Sudan.

In 1864 Sir Samuel Baker, an English explorer, became the first European to visit the lake. He named it for Prince Albert, husband of Queen Victoria.
