The 1972 Queen's Birthday Honours were appointments to orders and decorations of the Commonwealth realms to reward and highlight citizens' good works, on the occasion of the official birthday of Queen Elizabeth II. They were announced in supplements to the London Gazette of 23 May 1972 for the United Kingdom, Australia, New Zealand, Mauritius, Fiji, and Barbados. At this time honours for Australians were awarded both in the United Kingdom honours on the advice of the premiers of Australian states, and also in a separate Australia honours list.
