This is a list of ambassadors of the United States to Cambodia.
Until 1953 Cambodia had been French protectorate as a part of French Indochina, but became independent on November 9, 1953. The United States had appointed its first envoy to Cambodia, Donald R. Heath, in 1950. Heath was a non-resident minister who was commissioned to Cambodia, Laos, and Vietnam, while resident in Saigon.
Diplomatic relations between Cambodia and the United States were broken twice: The first time between 1965 and 1969, and the second time in 1975 just before the Khmer Rouge regime gained control of the country. Relations were finally restored in 1991.
The U.S. Embassy in Cambodia is located in Phnom Penh.
