The Republic of Vietnam Campaign Medal, also known as the Vietnam Campaign Medal, is a South Vietnamese military campaign medal which was created in 1949, and awarded to French military personnel during the First Indochina War. During the Vietnam War, the South Vietnamese government awarded the Republic of Vietnam Campaign Medal with Device to members of the South Vietnamese military for wartime service and on March 24, 1966, to members of the U.S. military for support of operations in Vietnam. In May 1966, other allied foreign military personnel became eligible for the award.

The awards and decorations of the United States Armed Forces include various medals, service ribbons, ribbon devices, and specific badges which recognize military service and personal accomplishments of members of the U.S. Armed Forces. Such awards are a means to outwardly display the highlights of a service member's career.
