The Porto-Novo Lagoon is a major hydrographic feature in southeastern Benin, connecting Lake Nokoué to the west with the Badagry River and the Lagos lagoon system in Nigeria to the east. Named after the Beninese capital, Porto-Novo, which sits on its northern shore, the lagoon has for centuries played a central role in regional trade and transport. The brackish water body is fringed by mangroves and marshes that, despite increasing urbanization, provide essential ecological functions. The lagoon serves as a significant fishing ground for local communities and is a vital corridor for inland water navigation between Benin and Nigeria. Its dynamics are heavily influenced by the Atlantic tides and the freshwater inflow from the Ouémé Delta. Historically a strategic site for colonial trade, it remains a vital resource for the economy of the capital region today.
