The 311th Cavalry Regiment was a cavalry unit of the United States Army during World War I and the interwar period. It was activated in early 1918 but broken up later that year to form new artillery units. The unit was recreated as a Texas Organized Reserve unit during the interwar period. It was disbanded after the United States entered World War II.

Shortly after the United States entered World War I, the regiment was constituted in the National Army on 18 May 1917, and organized on 15 February 1918 at Fort Riley. However, it was broken up on 1 September and its men were used to create the 67th and 68th Field Artillery Regiments, and the 23rd Trench Mortar Battery. All three artillery units were demobilized at Camp Knox on 22 December 1918.

On 15 October 1921, the 67th and 68th Field Artillery and the 23rd Trench Mortar Battery were reconstituted in the Organized Reserve as the 311th Cavalry Regiment, part of the 63rd Cavalry Division in the Second Corps Area. It was transferred to the Eighth Corps Area on 14 November. The 311th was initiated (activated) on 23 August 1922 with regimental headquarters and 1st Squadron at San Antonio, and 2nd Squadron at Fort Worth. The regiment joined the division's 156th Cavalry Brigade. It was reorganized on 1 July 1929 as a three-squadron regiment, with the new 3rd Squadron activated at Tucson. In February 1932, regimental officers organized the Cavalry Club of the Southwest in San Antonio. The 2nd and 3rd Squadrons were moved to Houston and Dallas, respectively, in March 1937. 3rd Squadron personnel in Tucson joined the 2nd Squadron, 312th Cavalry Regiment.
