The 4th Light Horse Regiment was a mounted infantry regiment of the Australian Army during the First World War. The regiment was raised in August 1914, as the divisional cavalry regiment for the 1st Division. The regiment fought against the forces of the German Empire and the Ottoman Empire, in Egypt, at Gallipoli, on the Western front, 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 twenty-one battle honours.

During the inter-war years, the regiment was re-raised as a part-time unit based in the Corangamite region of southern Victoria. It was later converted to a motor regiment during the Second World War but was disbanded in late 1944 without having been deployed overseas. In the post war period, the regiment was re-raised as an amalgamated unit, designated the 4th/19th Prince of Wales's Light Horse, which is currently part of the Australian Army Reserve.
