The 9th Queen's Royal Lancers was a cavalry regiment of the British Army, first raised in 1715. It saw service for three centuries, including the First and Second World Wars. The regiment survived the immediate post-war reduction in forces, but was amalgamated with the 12th Royal Lancers to form the 9th/12th Royal Lancers in 1960.
