The 315th 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 Rhode Island, Connecticut, Vermont, and Massachusetts 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 30 March 1918 at Fort D.A. Russell, commanded by Colonel Walter Cowan Short. It was broken up on 19 August 1918 into the 71st and 72nd Field Artillery Regiments and the 24th Trench Mortar Battery. All three artillery units were demobilized at Camp Knox on 30 January 1919.

On 15 October 1921, the 71st and 72nd Field Artillery and the 24th Trench Mortar Battery were reconstituted in the Organized Reserve as the 315th Cavalry Regiment, part of the 64th Cavalry Division in the Fifth Corps Area. On 14 November, it was transferred to the First Corps Area. The 315th was initiated (activated) on 19 January 1922 with regimental headquarters at Providence, Rhode Island, 1st Squadron at Hartford, Connecticut, and 2nd Squadron at New Haven, Connecticut. In 1923, a regimental band was initiated at Providence. In July 1924, the regiment participated in a mounted march alongside the 1st Squadron, 3rd Cavalry Regiment from Fort Devens to Fort Ethan Allen. On 15 April 1926, the 1st Squadron was moved to Providence and the 2nd Squadron to Boston. At the time, regimental units were scattered over Rhode Island, eastern Massachusetts, and southern Vermont and New Hampshire. It was reorganized as a three-squadron regiment on 1 July 1929, with the new 3rd Squadron being initiated at Boston from the men of the disbanded 158th Machine Gun Squadron. Simultaneously, the 2nd Squadron moved back to New Haven. The regiment was attached to the 76th Division for organization, administration, and training between 17 October 1929 and 27 January 1930 before transferring to the 94th Division.
