Douglas Albert Munro was a United States Coast Guardsman who was posthumously decorated with the Medal of Honor for an act of "extraordinary heroism" during World War II. He is the only person to have received the medal for actions performed during service in the Coast Guard.

The United States Coast Guard (USCG) is the maritime security, search and rescue, and law enforcement service branch of the United States Armed Forces and one of the country's eight uniformed services. The service is a maritime, military, multi-mission service unique among the United States military branches for having a maritime law enforcement mission with jurisdiction in both domestic and international waters and a federal regulatory agency mission as part of its duties. It is the largest coast guard in the world, rivaling the capabilities and size of most navies.
