The 1913 Birthday Honours were appointments in the British Empire of King George V to various orders and honours to reward and highlight good works by citizens. The appointments were made to celebrate the official birthday of The King, and were published on 3 June 1913 and 6 June 1913.

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.
