Pudjo Prasetyo is an Indonesian military officer and diplomat who served as Indonesia's ambassador to Laos from 1980 to 1982 and to Vietnam from 1982 to 1986. Prior to his ambassadorships, he took on roles as military attaché in North Vietnam and as the last acting director general of the International Commission of Control and Supervision.
During the Vietnam War, Pudjo, then a colonel, served as Indonesia's military attaché at the embassy in North Vietnam. According to Central Intelligence Agency reports, Pudjo received information from his Eastern Bloc counterparts regarding the presence of detained US soldiers there. He continued his involvement in the Vietnam War, and by 1975 he became the acting director general of the International Commission of Control and Supervision (ICCS). Pudjo served until Indonesia's withdrawal from the ICCS on 26 April that year, and he was not replaced until ICCS was dissolved after the Fall of Saigon four days later.
By 1976, Pudjo joined the foreign ministry and became the chief of the ministry's organizational affairs. On 3 May 1980, Pudjo, already a brigadier general, was sworn in as Indonesia's ambassador to Laos. He presented his credentials to president Souphanouvong on 6 August and met with premier Nouhak Phoumsavanh nine days later. At the end of his tenure, he paid farewell calls to several key Laotian officials. He visited Souphanouvong on 7 August and deputy prime minister Phoumi Vongvichit and Sali Vongkhamsao on 21 August 1982. He was then reassigned to Vietnam on the same year after his approval as Indonesia's ambassador to Vietnam was announced by the foreign minister on 6 June that year. Shortly before the end of his term, in January 1986 he briefed president Suharto regarding bilateral relations with Vietnam, in which he stated Indonesia's plans to sell a hundred thousand tonnes of rice to Vietnam and on Vietnam's wishes for Indonesia to act as a mediator regarding its conflict with Cambodia. Pudjo departed Hanoi on the 27th of November that year.
