The 2nd 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in April 1918 when three brigades already in Palestine were merged with elements of the 2nd Indian Cavalry Division withdrawn from the Western Front. In July 1918, the division was renamed as the 5th Cavalry Division. It remained in Palestine after the end of the war on occupation duties until finally broken up in 1920.

The 2nd Indian Cavalry Division was a division of the British Indian Army formed at the outbreak of World War I. It served on the Western Front, being renamed as 5th Cavalry Division on 26 November 1916. In March 1918, the 5th Cavalry Division was broken up. The British and Canadian units remained in France and the Indian elements were sent to Egypt to help constitute 2nd Mounted Division.
