French Cochinchina was a colony of French Indochina, encompassing the whole region of Lower Cochinchina or Southern Vietnam from 1862 to 1946. The French operated a plantation economy whose primary strategic product was rubber.

French Indochina, officially known as the Indochinese Union and after 1947 as the Indochinese Federation, was a grouping of French colonial territories in Mainland Southeast Asia until its end in 1954. It comprised Cambodia, Laos, the Chinese territory of Guangzhouwan, and the Vietnamese regions of Tonkin in the north, Annam in the centre, and Cochinchina in the south. The capital for most of its history (1902–1945) was Hanoi; Saigon was the capital from 1887 to 1902 and again from 1945 to 1954.
