Senegambia and Niger was a short-lived administrative unit of the French possessions in Africa, formed in 1902 and reorganized in 1904 into Upper Senegal 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". The set consisted of 13 values, from 1 centime to 1 franc. For stamp collectors today, the price ranges from 1 US$ for the low values and up for 40 US$ for the 1-franc value.
