Navy Region Southwest is one of eleven current naval regions responsible to Commander, Navy Installations Command for the operation and management of Naval shore installations in California, Nevada, Utah, Arizona, Colorado, New Mexico. It is headquartered across from the Broadway Pier in Downtown San Diego. The command also serves as the regional coordinator for the Commander, U.S. Pacific Fleet, headquartered in Hawaii, coordinating support for bases in Southern California and Nevada.

The Commander also serves as regional environmental coordinator for California, Arizona and Nevada and coordinates and oversees environmental compliance actions with local, state and federal regulatory agencies. Additionally, COMNAVREGSW is responsible for planning and coordinating Department of the Navy response to civil emergencies within the states of Nevada, Utah, Colorado, Arizona and California.

Navy Region Southwest comprises the former areas of the Eleventh and Twelfth Naval Districts.

The Eleventh and Twelfth Naval Districts, were both established on 7 May 1903 in accordance with General Order No. 128, signed by Acting Secretary of the Navy Charles H. Darling. The Eleventh Naval District was to be headquartered at the Lake Training Station in Lake Bluff, Illinois, while the Twelfth was to be headquartered at the Mare Island in Vallejo, California. Both districts were part of a larger administrative unit known as the "Ninth, Tenth and Eleventh Naval Districts".

In 1919 when the Ninth, Tenth and Eleventh Districts were split, the Eleventh Naval District, then known as Commander Navy Southwest, established headquarters for the first Commander with a staff of seven officers at Naval Station North Island. In 1922, when the Naval Supply Center buildings at the foot of Broadway Street on Harbor Drive were completed, the Naval Base Headquarters moved to its present site.
