François Bizot (born February 8, 1940 in Nancy, France) was the only Westerner to survive imprisonment by the Khmer Rouge.

Bizot arrived in Cambodia in 1965 to study Buddhism practiced in the countryside. He traveled extensively around Cambodia, researching the history and customs of its dominant religion. He speaks fluent Khmer, French and English and was married to a Cambodian. When the Vietnam War spilled into Cambodia, Bizot was employed at the Angkor Conservation Office, restoring ceramics and bronzes.

In October 1971, Bizot and his two Cambodian colleagues were captured by the Khmer Rouge. During his captivity on charges of being a CIA agent at the Khmer Rouge Camp M.13 at Anlong Veng, he developed a strangely close relationship with his captor, Comrade Duch, who later became the Director of the infamous Tuol Sleng concentration camp in Phnom Penh. During his three-month imprisonment he came to understand the true genocidal nature of the Khmer Rouge long before other outsiders. He was finally released in December 1971 after Comrade Duch wrote a detailed report that convinced the Khmer Rouge leadership of Bizot's innocence. Bizot's Cambodian colleagues were executed soon after Bizot's release.
When the Khmer Rouge poured into Phnom Penh in April 1975, Bizot, like most other foreigners in the country, wound up in the French Embassy in Phnom Penh. Because of his fluency in Khmer, he soon became the primary point of contact and unofficial translator between the embassy officials and the Khmer Rouge. He left Cambodia when the Khmer Rouge expelled all foreigners and sealed off Cambodia's borders. He returned to Cambodia in 2000 and met his former captor Duch, then awaiting trial for crimes against humanity.

Bizot lives in Paris now. He is the Director of Studies at École Pratique des Hautes Études and holds the chair in Southeast Asian Buddhism at the Sorbonne.
