town and Atlantic fishing port, western Liberia. It is situated at the outlet of Lake Piso (Fisherman Lake), on Cape Mount.

In 1461 or 1462 the Portuguese navigator Pedro de Sintra reached the cape, a 1,000-foot- (305-metre-) high granite promontory, which he named Cabo do Monte. In the early 19th century a colony of North American freed slaves settled the site, which was part of the Vai territory.

Robertsport (named after Liberia's first president, Joseph Jenkins Roberts (Roberts, Joseph Jenkins)) is connected with Monrovia by air and by road. The town is situated in an area of heavy rainfall, averaging some 205 inches (5,200 mm) annually. The inhabitants are engaged mainly in fishing and rice farming. Pop. (latest est.) 7,000.
