The Loyalty Medal (Vietnamese: Trung-Chánh Bội-Tinh) was a single-grade decoration awarded by South Vietnam. Established in 1964, the medal was awarded to South Vietnamese citizens by the Chief of the Joint General Staff, Republic of Vietnam Military Forces. The medal could be awarded posthumously.
The Loyalty Medal was awarded to Vietnamese citizens who had shown proven loyalty to the "National Cause" by denouncing or working to counter, what were deemed by the South Vietnamese government to be, subversive activities that were disruptive to security and order.[1]
