Joint Region Marianas (JRM) is a joint United States military command located on Guam. It is the installation management authority for both Andersen Air Force Base and Naval Base Guam. Its headquarters is located halfway between the two installations, on Nimitz Hill. The command is an amalgamation of the United States Navy Naval Base Guam and the United States Air Force Andersen Air Force Base which were merged on October 1, 2009.

JRM was established in accordance with congressional legislation implementing the recommendations of the 2005 Base Realignment and Closure Commission. The legislation ordered the consolidation of facilities which were adjoining, but separate military installations, into a single joint base, one of 12 formed in the United States as a result of the law.

On February 6, 2009, the Navy and Air Force held a groundbreaking ceremony for a combined headquarters at Nimitz Hill, signaling the beginning of Joint Region Marianas. Joint Region Marianas began initial operational capability on Jan. 31, 2009, and reached full operational capability on October 1, 2009.

Under Joint Region Marianas, U.S. Naval Base Guam and Andersen Air Force Base will each maintain commanding officers, who will oversee their respective mission requirements and operations. Joint Region Marianas will oversee support services, policies, and resources. Joint Region Marianas is symbolic of the historic partnership between the Navy and Air Force on Guam, bridging the approximately 30 miles between U.S. Naval Base Guam and Andersen Air Force Base.

The commander of Joint Region Marianas also serves as commander of U.S. Naval Forces Marianas and as U.S. Defense Representative to Guam, Commonwealth of the Northern Mariana Islands, Republic of Palau, and Federated States of Micronesia.

Naval Base Guam is home of Commander Submarine Squadron 15, Coast Guard Sector Guam and Naval Special Warfare Unit One and supports 28 other tenant commands. It is the home base of dozens of Pacific Command, United States Pacific Fleet, and Seventh Fleet units.
