Hugh Alexander Dunn AO (20 August 1923 – 5 November 2005) was a career Australian diplomat known for his knowledge of China; namely Taiwan (1969–1972) and of the People's Republic of China (1980–1984).
After completing school at Brisbane Boys' College, he enlisted in the A.I.F., trained in Signals Intelligence and moved with MacArthur's troops through New Guinea and then to the Philippines where the Japanese surrender took place.
He was awarded a Rhodes Scholarship to Oxford University[2] where he studied classical Chinese language, history and philosophy.
In the 1985 Queen's Birthday Honours he was appointed an Officer of the Order of Australia for "services to the public service, particularly in the field of international relations and in the development of Australian relations with China".
He wrote extensively on Sino-Australian relations and the teaching of the Chinese language.
