Senegambia and Niger was a short-lived administrative unit of the colonial French West Africa possessions, in the region of present-day Niger, Mali and Senegal.
It was formed in 1902, and reorganized in 1904 into Upper Senegal and Niger.[1]
See main article: Postage stamps and postal history of Senegambia and Niger. Despite its brief existence, the French government still managed to issue postage stamps for the administrative unit, in the form of a version of its Navigation and Commerce series, inscribed "SENEGAMBIE / ET NIGER".
