This map, drawn by French geographer Jules-Léon Dutreuil de Rhins and published by the French Navy's cartographic department in 1881, shows the territorial administration of French Cochinchina.

French Cochinchina was one of the five colonies into which the French territory in Southeast Asia known as Indochina was subdivided. It corresponds to the southern region of present-day Vietnam, a point of particular importance as it is the mouth of the Mekong River, one of the most important rivers in Asia.

On the map, this region appears divided into six constituent provinces, which correspond to the six provinces into which the region was already divided before it was taken over by the French: Gia Định, Biên Hòa, Định Tường, Vĩnh Long, An Giang and Hà Tiên.
