Cotonou
Benin's largest city and port, built between the sea and the Nokoué lagoon.
Updated 16 October 2026
Cotonou is where Benin does its business: the country's main port, its airport and its largest population, built on the strip between the Atlantic and Lake Nokoué and crossed by lagoon channels. It is not the capital, which remains Porto-Novo, but it holds the government in practice. Motorcycle taxis called zemidjans move most people, and the Dantokpa market on the lagoon is the commercial heart of the whole region.
Background
Early in the 19th century the site was a small fishing village, then spelled Kutonou, and King Ghezo of Dahomey is thought to have formally founded the town in 1830. A canal dug in 1855, the lagoon of Cotonou, divides the city in two, and three bridges cross it. Growth picked up quickly once the harbour was built in 1908, yet the population was only 70,000 in 1960. By 2012 the city proper held 679,012 people, and over two million live in the wider urban area. A UNEP pilot project found that the coast east of the city had retreated by 400 meters in 40 years.
