The 10th Light Horse Regiment is a "light cavalry"regiment of the Australian Army Reserve, raised in Western Australia (WA).

While the name of the 10th Light Horse originated in the first months of World War I, the regiment traces its ceremonial lineage to mounted infantry units of the Colonial militia of Western Australia, raised during the late 19th century, such as the Western Australian Mounted Infantry. Consequently, its battle honours include: "South Africa" (Boer War) and; "Gallipoli", "Gaza-Beersheba", "Jerusalem", "Megiddo" and "Damascus" (World War I).

At present, Bushmaster Protected Mobility Vehicle and 6x6 Surveillance & Reconnaissance Vehicles – a variant of the Mercedes-Benz G-Wagon – comprise the regiment's key operational vehicles. It is part of the 13th Brigade, a reserve formation encompassing most reserve personnel in WA and is based at Irwin Barracks, Karrakatta, where it consists of one squadron. Because of its operational role, the regiment's administrative grouping is the Royal Australian Armoured Corps.
