The 1914–15 Star is a campaign medal of the British Empire which was awarded to officers and men of British and Imperial forces who served in any theatre of the First World War against the Central European Powers during 1914 and 1915. The medal was never awarded singly and recipients were also awarded the British War Medal and Victory Medal.

The medal was initially not going to be awarded to soldiers who served in the Gallipoli Campaign. Those soldiers, mostly New Zealanders and Australians, were to be awarded the Gallipoli Star instead.

The Commonwealth Gallipoli Star, originally to have been called the Anzac Star, was proposed by Lieutenant General Birdwood for Australian and New Zealand troops who served at Gallilopi. Despite approval by George V, protest at a medal that could not be awarded to all Commonwealth troops was raised by British parliamentarians and the media. In 1918, after ribbons, but not medals had been shipped, the award was cancelled and instead eligible soldiers were awarded the 1914 -15 Star. In 1990 the award was privately struck with 200 copies given to Gallipoli veterans and 1800 sold to collectors.
