La Lutte was a left-wing paper published in Saigon, French-colonial Cochinchina, in the 1930s. It was launched ahead of the April–May 1933 Saigon municipal council election as a joint organ of the Indochinese Communist Party (PCI) and a grouping of Trotskyists and others who agreed to run a joint "Workers' slate" of candidates for the polls. This kind of cooperation between Trotskyists and Comintern-linked communists was a phenomenon unique to Vietnam. The editorial line of La Lutte avoided criticism of the USSR while supporting the demands of workers and peasants without regard to faction. The supporters of La Lutte were known as lutteurs.

Trotskyism in Vietnam was represented by those who, in left opposition to the Indochinese Communist Party (ICP) of Nguyen Ai Quoc, identified with the call by Leon Trotsky to re-found "vanguard parties of proletariat" on principles of "proletarian internationalism" and of "permanent revolution". Active in the 1930s in organising the Saigon waterfront, industry and transport, Trotskyists presented a significant challenge to the Moscow-aligned party in Cochinchina. Following the September 1945 Saigon uprising against the restoration of French colonial rule, Vietnamese Trotskyists were systematically hunted down and eliminated by both the French Sûreté and the Communist-front Viet Minh.
