The commandant of the Coast Guard is the service chief and highest-ranking member of the United States Coast Guard. The commandant is an admiral, appointed for a four-year term by the president of the United States upon confirmation by the United States Senate. The commandant is assisted by a vice commandant, who is also an admiral, and two area commanders and two deputy commandants, all of whom are vice admirals.

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.
