In 1999, the northern section of Ouémé was split off to form the department of Plateau.

Ouémé Department borders Zou Department to the north, Plateau Department to the northeast, Nigeria to the southeast, the Atlantic Ocean to the south, Littoral Department to the southwest, and Atlantique Department to the west. It is located in a coastal area that has interconnected lakes and lagoons and elongated coastlines with wide marshes. The southern regions of Benin receive two spells of rain from March to July and September to November, while the northern regions of the country receive one season of rainfall from May to September. The country receives an average annual rainfall of around 1,200 mm (47 in), but Ouémé Department receives less rainfall. The department has mostly low-lying sandy coastal plains towards the Atlantic Ocean, marshes, lagoons and lakes, including part of Lake Nokoué in the southwest. The highest elevation in the department around the coastal plains is 20 m (66 ft) compared to the average 200 m (660 ft) above average mean sea level of the country.
Freshwater and seawater fishing is the major profession in the region. Petroleum was discovered in the 1960s in offshore areas, while titanium, low quality iron ore, ilmenite and chromite are the major minerals.

Benin originally had six administrative regions (départements), which have now been bifurcated to make 12. Each of the deconcentrated administrative services (directions départementales) of the sectoral ministries takes care of two administrative regions. A law passed in 1999 transformed the sous-prefectures, the lowest level of territorial administration, into local governments. Municipalities and communal councils have elected representatives who manage the administration of the regions. The latest elections of the municipal and communal councils were held in June 2015.
