The 1st Mounted Division was a cavalry division that served as part of the Egyptian Expeditionary Force in Palestine in World War I. It was formed in April 1918 when the Yeomanry Mounted Division was merged with elements of the 1st Indian Cavalry Division withdrawn from the Western Front. In July 1918, the combined division was renamed as the 4th Cavalry Division. It remained in Palestine after the end of the war on occupation duties until finally broken up in 1921.
