7th Missouri Cavalry Regiment was a cavalry unit from Missouri that served in the Union Army during the American Civil War. The regiment was formed on 20 February 1862 by merging Bishop's Cavalry Battalion (also known as the Blackhawk Cavalry, which had formed on 14 November 1861) with some unattached cavalry companies. The regiment fought at Independence, Lone Jack, Prairie Grove and Van Buren in 1862. The unit participated in Frederick Steele's expedition to Little Rock in 1863, fighting at Brownsville, Ashley's Mills, and Bayou Fourche. In 1864, the regiment went on the Camden Expedition and fought at Mount Elba and Marks' Mills. The remaining soldiers were consolidated with the 1st Missouri Volunteer Cavalry Regiment on 22 February 1865.
