The 1919 Birthday Honours were appointments by King George V to various orders and honours to reward and highlight good works by citizens of the British Empire. The appointments were made to celebrate the official birthday of The King, and were published in The London Gazette from 3 June to 12 August. The vast majority of the awards were related to the recently ended War, and were divided by military campaigns. A supplementary list of honours, retroactive to the King's birthday, was released in December 1919. The new peers and baronets were not announced until August.
