This is a list of rivers in Benin. This list is arranged west to east by drainage basin, with respective tributaries indented under each larger stream's name.
Benin is divided into 12 departments (French: départements), and subdivided into 77 communes (see Communes of Benin). In 1999, the previous six departments were each split into two halves, forming the current 12. The new six departments have been assigned a capital in 2008.
Porto-Novo (also known as Hogbonou and Adjacé) is the official capital of the West African nation of Benin, and was the capital of French Dahomey. The commune covers an area of 110 square kilometres (42 sq mi) and as of 2002 had a population of 223,552 people.
