Communism in Vietnam is linked to the Politics of Vietnam and the push for independence. Marxism was introduced in Vietnam with the emergence of three communist parties: the Indochinese Communist Party, the Annamese Communist Party, and the Indochinese Communist Union, later joined by a Trotskyist movement led by Tạ Thu Thâu. In 1930, the Communist International (Comintern) sent Nguyễn Ái Quốc to Hong Kong to coordinate the unification of the parties into the Vietnamese Communist Party, with Trần Phú as its first Secretary General.

Ho Chi Minh Thought is a political philosophy that builds upon Marxism–Leninism and the ideology of Vietnamese revolutionary Ho Chi Minh. It was developed and codified by the Communist Party of Vietnam and formalised in 1991. The term is used to cover political theories and policies considered as representing a form of Marxism–Leninism that has been adapted to Vietnamese circumstances and history. The ideology includes views on the basic issues of the Vietnamese Revolution, specifically the development and application of Marxism–Leninism to the material conditions of Vietnam.
