Porto-Novo (also known as Hogbonou and Adjacé (population 223,552 as of a 2002 census) is the official capital of the West African nation of Benin. It is a port on an inlet of the Gulf of Guinea, in the southeastern portion of the country. Porto-Novo is Benin's second largest city, but the city of Cotonou is more important, culturally and politically. The region around Porto-Novo produces palm oil, cotton and kapok. Petroleum was discovered off the coast of the city in the 1990s, and has become an important export.
Porto-Novo is located at 6°28' North, 2°36' East (6.46667, 2.6).
