The Military Order of the Loyal Legion of the United States (MOLLUS), or simply the Loyal Legion is a United States patriotic order, organized April 15, 1865, by three veteran officers of the Army. The original membership was composed of members of the Army, Navy, or Marine Corps of the United States, who had served during the American Civil War as commissioned officers in Federal service, or who had served and thereafter been commissioned, and who thereby "had aided in maintaining the honor, integrity, and supremacy of the national movement" during the Civil War.
