The 24th Infantry Regiment is a unit of the United States Army, active from 1869 until 1951, and since 1995. Before its original dissolution in 1951, it was primarily made up of African American soldiers.

Buffalo Soldiers were United States Army regiments composed primarily of African Americans, formed during the 19th century to serve on the American frontier. On September 21, 1866, the 10th Cavalry Regiment was formed at Fort Leavenworth, Kansas. The nickname "Buffalo Soldiers" was purportedly given to the regiment by Native Americans who fought against them in the American Indian Wars, and the term eventually became synonymous with all of the African American U.S. Army regiments established in 1866, including the 9th Cavalry Regiment, 10th Cavalry Regiment, 24th Infantry Regiment, 25th Infantry Regiment and 38th Infantry Regiment.
