The Phoenix Program (Vietnamese: Chiến dịch Phụng Hoàng) was designed and initially coordinated by the United States Central Intelligence Agency (CIA) during the Vietnam War, involving the American, Australian, and South Vietnamese militaries. In 1970, CIA responsibility was phased out, and the program was put under the authority of the Civil Operations and Revolutionary Development Support (CORDS).
The program, which lasted from 1967 to 1972, was designed to identify and destroy the Viet Cong (VC) via infiltration, assassination, torture, capture, counter-terrorism, and interrogation. The CIA described it as "a set of programs that sought to attack and destroy the political infrastructure of the Viet Cong." The Phoenix Program was premised on the idea that North Vietnamese infiltration had required local support within noncombat civilian populations, which were referred to as the "VC infrastructure" and "political branch" that had purportedly coordinated the insurgency.
Throughout the program, Phoenix "neutralized" 81,740 people suspected of VC membership, of whom 26,369 were killed, and the rest surrendered or were captured. Of those killed 87% were attributed to conventional military operations by South Vietnamese and American forces, while the remaining 13% were attributed to Phoenix Program operatives.: 17–21 
The Phoenix Program was heavily criticized on various grounds, including the number of neutral civilians killed, the nature of the program (which critics have labelled as a "civilian assassination program,") the use of torture and other coercive methods, and the program being exploited for personal politics. Nevertheless, the program was very successful at suppressing Viet Cong political and revolutionary activities. Public disclosure of the program led to significant criticism, including hearings by the US Congress, and the CIA was pressured into shutting it down. A similar program, Plan F-6, continued under the government of South Vietnam.
