The 15th/19th The King's Royal Hussars was a cavalry regiment of the British Army. It was created as part of the reduction in cavalry in the aftermath of the First World War. It was formed by the amalgamation of the 15th The King's Hussars and the 19th Royal Hussars (Queen Alexandra's Own) on 11 April 1922, becoming the 15th/19th Hussars. It briefly dropped the 19th numeral from its title in 1932, becoming the 15th The King's Royal Hussars, before regaining it the following year.
