The 14th Light Horse Regiment was a mounted infantry or light horse unit of the Australian Army. The unit takes its lineage from units raised as part of the colonial forces of the state of Queensland in 1860 and served during the Second Boer War and World War I. In 1930 it was amalgamated with the 2nd Light Horse Regiment to become the 2nd/14th Light Horse Regiment, a unit that continues to exist as part of the Australian Army today.

Australian Light Horse were mounted troops with characteristics of both cavalry and mounted infantry, who served in the Second Boer War and World War I. During the inter-war years, a number of regiments were raised as part of Australia's part-time military force. These units were gradually mechanised either before or during World War II, although only a small number undertook operational service during the war. A number of Australian light horse units are still in existence today.
