The 12th Virginia Cavalry Regiment was a cavalry regiment raised in Virginia for service in the Confederate States Army during the American Civil War. It fought mostly with the Army of Northern Virginia.
Virginia's 12th Cavalry Regiment (originally called 10th Regiment) was organized at Conrad's Store, Virginia, in June 1862, with ten companies from the 7th Virginia Cavalry regiment, which consisted of twenty-nine companies at the time.
The unit served in W.E. Jones', Rosser's, and J. Dearing's Brigade, Army of Northern Virginia. It fought in Northern Virginia, in the Maryland Campaign, at Brandy Station, then was involved in various conflicts in the western part of Virginia. The regiment continued the fight at Bristoe and Mine Run, in the battles around The Wilderness and Cold Harbor, and in Early's operations in the Shenandoah Valley.
During mid-April, 1865, it disbanded. The field officers were Colonel Asher W. Harman, Lieutenant Colonels Richard H. Burks and Thomas B. Massie, and Major John L. Knott.
