The Korean Service Medal (KSM) is a military award for service in the United States Armed Forces and was created in November 1950 by executive order of President Harry Truman. The Korean Service Medal is the primary US military award for participation in the Korean War and is awarded to any US service member who performed duty in South Korea between June 27, 1950 and July 27, 1954.
The United States Department of Defense declared thirteen official campaigns of the Korean War, all of which are annotated by service stars on the Korean Service Medal. Some campaigns apply to all branches of the US military, while others are branch specific. The Korean Service Medal is authorized a service star to denote participation in any of the following campaigns:
- North Korean Aggression (USMC, Navy): June 27 to November 2, 1950
- United Nations Defensive (Army, USAF): June 27 to September 15, 1950
- Inchon Landing (USMC, Navy): September 13 to 17, 1950
- United Nations Offensive (Army, USAF): September 16 to November 2, 1950
- Chinese Communist Forces Intervention (Army, USAF): November 3, 1950 to January 24, 1951
- Communist China Aggression (USMC, Navy): November 3, 1950 to January 24, 1951
- First United Nations Counteroffensive (USMC, Army, Navy, USAF): January 25 to April 21, 1951
- Chinese Communist Forces Spring Offensive (USMC, Army, Navy, USAF): April 22 to July 8, 1951

Fleet Marine Force combat operation insignia
- The Fleet Marine Force Combat Operation Insignia is authorized for US Navy personnel who served with the Marine Corps at any time during the Korean War.
Although the Korean War Armistice ended combat operations in Korea on 27 July 1953, the Korean Service Medal was issued until June 1954 due to the tense nature of the occupation and garrison duty immediately after the armistice, as well as the high possibility of a renewed attack by North Korea. After 1954, the Korean Service Medal was no longer issued although the Armed Forces Expeditionary Medal was authorized for Korean service in the 1960s. As of 2004, a new medal known as the Korea Defense Service Medal was authorized for all post-Korean War service in the Republic of Korea.
The KSM was designed by the Army Heraldic Section. The color scheme of the ribbon is derived from the Flag of the United Nations, as it was under the auspices of the United Nations (United Nations Security Council Resolution 82) that the war was conducted. The medal itself features a "Korean gateway," most likely an iljumun, on the front, and a taegeuk on the reverse. 
The United Nations Service Medal for Korea was usually issued alongside the Korean Service Medal. Beginning in 1999, the Republic of Korea War Service Medal was also awarded to United States service members who received the Korean Service Medal. The Republic of Korea Presidential Unit Citation is retroactively authorized to any United States Army veteran who served in Korea during the War.
