Nguy?n An Ninh (September 5, 1900 – August 14, 1943) was a radical Vietnamese political journalist and publicist in French colonial Cochinchina (southern Vietnam).
An independent and charismatic figure, Nguyen An Ninh was able to conciliate between different anti-colonial factions including, for a period in the 1930s, between the Communist Party of Nguyen Ai Quoc ("Ho Chi Minh", then in exile) and its left, Trotskyist, opposition.
Nguyen An Ninh died in the French penal colony of Pulo Condore, age 42.
He is recognised by the Socialist Republic of Vietnam as a Revolutionary Martyr.
