The King's Birthday Honours 1923 were appointments in many of the Commonwealth realms of King George V 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 King. They were published on 1 and 29 June 1923.

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.
