The 11th Light Horse Regiment was a mounted infantry regiment of the Australian Army during the First World War. The regiment was raised in August 1914, and assigned to the 4th Light Horse Brigade. The regiment fought against the forces of the Ottoman Empire, in Egypt, at Gallipoli, on the Sinai Peninsula, and in Palestine and Jordan. After the armistice the regiment eventually returned to Australia in March 1919. For its role in the war the regiment was awarded fourteen battle honours. During the inter-war years, the regiment was re-raised as a part-time unit based in the Darling Downs region of Queensland. It was later converted to a motor regiment during the Second World War but was disbanded in 1943 without having been deployed overseas.
