Win Aung (Burmese: ဝင်းအောင်) was a Burmese military officer and politician who served as the Minister of Foreign Affairs from 1998 until 2004.

Win Aung was born in Dawei (formerly Tavoy), Tanintharyi Division in 1944. Win Aung would later join the armed forces, where he would serve as a military intelligence officer.

Win Aung served as an ambassador to Germany and the UK until he was appointed as Minister of Foreign Affairs in November 1998. During his tenure as foreign minister, he often bore the brunt of international criticism on many issues, especially for his government's repression of political dissidents such as Aung San Suu Kyi, while visiting foreign nations. In September 2004, he was dismissed from his post, along with several other ministers, following a purge of members of the Military Intelligence faction of the State Peace and Development Council.

Win Aung was a close associate of former Prime Minister Khin Nyunt, who was among those purged in September 2004. Following his dismissal, Win Aung was arrested and sent to the notorious Insein Prison. He died there on 4 November 2009 at the age of 65. At the time of his death, he was the only former Burmese government minister to be imprisoned.

Thet Win Aung (သက်ဝင်းအောင် [θɛʔ wɪ́ɴ àʊɴ]; 27 August 1971 – 16 October 2006) was a Burmese student activist.

He took part in the 1988 Movement as one of the leading members of his high school student union, Tamwe Township. In 1989, he was elected vice general secretary of the Basic Education Student Union (BESU). He was dismissed from his school for his political involvement in student demonstrations, later jailed for 9 months for aiding in forming the Student Union. In 1994, the MIs tried to arrest him again because he published the ABFSU pamphlets and organized student demonstrations to commemorate the 32nd anniversary of 7 July Affair. (In 1962, the military regime killed hundreds of the university students by dynamiting the student union building at the Yangon University.) Although he escaped, his home was searched frequently and his family was harassed incessantly while he was on his run. From behind the scenes, he took part in the 1996 student demonstrations and helped organized the student protests against the poor quality of education and students' rights in 1998. He was arrested in October 1998, and sentenced to 59 years in prison. At first, he was detained in Kalay Prison, Sagaing Division. He was moved to Khamti Prison, and transferred to the Mandalay Prison at 2004.
