French was the official language of Vietnam under French colonial rule during the 19th and early 20th centuries. After 1954, French fell into disuse in North Vietnam, and maintained a high status in South Vietnam. Since the Fall of Saigon in 1975, French has declined in modern Vietnam: in 2018, under 1% of the population was fluent in French.

A French pidgin called Tây Bồi was developed among Vietnamese servants in French households and those who spoke partial French. Nevertheless, at the French language's height in Vietnam between the 1900s and 1940s, many Vietnamese did not speak French well or learn the language and some revolutionaries refused to learn the colonial language, though ironically speeches and papers written to promote independence were written in French. During World War II, Japan briefly occupied Vietnam and established Vietnamese as the sole official and educational language. The influence of the French language in Vietnam slowly began to decline after World War II as revolutionary movements increased and their works began to be written more in Vietnamese.
