Australia's involvement in the Vietnam War, beginning with a small commitment of 30 military advisors in 1962, increased over the following decade to a peak of 7,672 Australian personnel following the Menzies Government's April 1965 decision to upgrade its military commitment to South Vietnam's security. By the time the last Australian personnel were withdrawn in 1972, the Vietnam War had become Australia's longest war, and was only recently surpassed by Australia's long term commitment of combat forces to the War in Afghanistan. It currently remains Australia's largest force contribution to a foreign conflict since the Second World War and was also the most controversial in Australian society since the conscription controversy during the First World War. Although initially enjoying broad support due to concerns about the spread of communism in Southeast Asia, a vocal anti-war movement developed in response to Australia's programme of conscription.

The withdrawal of Australia's forces from South Vietnam began in November 1970 when 8 RAR completed its tour of duty and was not replaced. A phased withdrawal followed, and by 11 January 1973 Australian involvement in hostilities in Vietnam had ceased. Nevertheless, Australian troops from the Australian Embassy Platoon remained deployed in the country until 1 July 1973, and Australian forces were deployed briefly in April 1975, during the Fall of Saigon, to evacuate personnel from the Australian embassy. Approximately 60,000 Australians served in the war; 521 were killed and more than 3,000 were wounded.

Australia's involvement in the Vietnam War was driven largely by the rise of communism in Southeast Asia after the Second World War, and the fear of its spread which developed in Australia during the 1950s and early 1960s. Following the end of the Second World War the French had sought to reassert control over French Indochina. In 1950 as the communist-backed Viet Minh, led by Ho Chi Minh, began to gain the ascendency in the First Indochina War, the Vietnamese nation had two parallel administrations; the Democratic Republic of Vietnam (DRV) (recognised by the Soviet Union and the People's Republic of China) and the State of Vietnam (SoV), an associated state in the French Union (recognised by the non-communist world). In 1954, after the defeat of the French at the Battle of Dien Bien Phu, the Geneva Accords of 1954 split the country geographically, with the DRV to the north of the 17th parallel and the SoV in the south.
