Get to know Cotonou
A sense of the place
Cotonou is the seat of government and largest city of Benin. The official city proper population was 679,012 in 2012; however, over two million people live in the larger urban area. The urban area continues to expand, notably toward the west. The city lies in the southeast of the country, between the Atlantic Ocean and Lake Nokoué. Cotonou is the seat of government of the Republic of Benin, where most of the government buildings are situated, government departments operate and foreign embassies are located, but the official capital, where the national legislature sits, is the smaller city of Porto-Novo.
