The Gambia, a country on the western coast of Africa, fronting the Atlantic Ocean. Senegal encloses the country on the other three sides. Straddling the Gambia River, the country extends eastward for about 320 km (200 mi) from the Atlantic Ocean. At its widest, this narrow country measures only about 50 km (30 mi) across.

The Gambia, also called Gambia, is the smallest country on the African mainland. Among African countries, only the Seychelles, a group of islands off the eastern coast, cover a smaller area. The port city of Banjul is the capital of The Gambia, but Serrekunda is the largest city.
