The Queen's Birthday Honours 1979 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. The appointments were made to celebrate the official birthday of the Queen. They were published for the United Kingdom in two tranches, first on 15 June 1979 and second on 25 June 1979. Other countries' lists were published on 15 June 1979: Australia, New Zealand, Barbados, Mauritius, Fiji, Bahamas, Papua New Guinea, Solomon Islands, Tuvalu, and Saint Lucia.
The recipients of honours are displayed here as they were styled before their new honour, and arranged by honour, with classes (Knight, Knight Grand Cross, etc.) and then divisions (Military, Civil, etc.) as appropriate.
