The Bight of Benin is a bight on the western African coast that extends eastward for about 400 miles (640 km) from Cape St. Paul to the Nun outlet of the Niger River. To the east it is continued by the Bight of Bonny (formerly Bight of Biafra). The bight is part of the Gulf of Guinea. The Republic of Benin and this bight were both named after the Benin Empire.
