Quantico (formerly Potomac) is a town in Prince William County, Virginia, United States. The population was 480 at the 2010 census.
Quantico is located just northwest of the Potomac River and just south of the Quantico Creek. The word Quantico is a derivation of the name of a Doeg village recorded by English colonists as Pamacocack.
Quantico is surrounded on three sides by one of the largest U.S. Marine Corps bases, Marine Corps Base Quantico. The base is the site of the Marine Corps Combat Development Command and HMX-1 (the presidential helicopter squadron), Officer Candidate School, and The Basic School. The United States Drug Enforcement Administration's training academy, the FBI Academy, the FBI Laboratory, the Naval Criminal Investigative Service, the United States Army Criminal Investigation Command, and the Air Force Office of Special Investigations headquarters are on the base. A replica of the USMC War Memorial stands at the entrance to the base.
As of 2013[update], the mayor is Kevin P. Brown.
