The Queen's Birthday Honours 1974 were appointments in many of the Commonwealth realms of Queen Elizabeth II to various orders and honours to reward and highlight good works by citizens of those countries. They were published on 7 June 1974 for the United Kingdom, Australia (for Papua New Guinea), New Zealand, Mauritius, Fiji, the Bahamas, and Grenada. At this time honours for Australians were still being awarded in the UK honours on the advice of the premiers of Australian states. The Australian honours system began with the 1975 Queen's Birthday Honours.
