The 7th Light Horse Regiment was a mounted infantry regiment of the Australian Army during the First World War. The regiment was raised in October 1914, and assigned to the 2nd 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 sixteen battle honours. During the inter-war years, the regiment was re-raised as a part-time unit based in New South Wales. It was later converted to a motor regiment during the Second World War but was disbanded in late 1943 without having been deployed overseas.
