The Ébrié Lagoon lies in Ivory Coast, separated for almost all of its length from the Atlantic Ocean by a narrow coastal strip. The long lagoon is linked to the sea by the Vridi Canal, while the Komoé River flows into it. The lagoon averages 4 km (2½ mi) in width, and in depth. Abidjan and towns such as Grand Bassam, Bingerville, Jacqueville, Attécoubé, and Tiagba lie on the lagoon.
Geography
The Ébrié Lagoon is a long narrow lagoon complex located in the south of Ivory Coast. It lies parallel with the coast on an east/west axis and consists of several linked lagoons. At the eastern end it is linked by a channel to the Aghien and Potou Lagoons, into which the Mé River flows. The other major rivers flowing into the lagoon are the Komoé River in the east, the Agnéby River in the centre, and the Ira River in the west. At the western end, Ébrié is linked by the Asagni Canal to the Tagba Lagoon and the Bandama River. It is connected to the Gulf of Guinea by the Vridi Canal, which was opened as a navigable channel in 1950. The natural mouth of the complex is at Grand-Bassam, but this tends to silt up during the dry season. There are several large and many small islands in the lagoon.

Parts of the lagoon are highly polluted. Chemical pollution comes from the agricultural and industrial activity in the catchment area, with fertiliser run off occurring particularly in the wet season. Organic and bacterial pollution occurs mainly in urban areas, with high levels of Escherichia coli and Clostridium perfringens being detected.
There is an artisanal fishery on the lagoon, employing about seven thousand people using four thousand boats with a potential annual catch of around .
