Fort MacArthur is a former United States Army installation in San Pedro, Los Angeles, California (now the port community of Los Angeles). A small section remains in military use by the United States Air Force as a housing and administrative annex of Los Angeles Air Force Base. The fort is named after Lieutenant General Arthur MacArthur. His son, Douglas MacArthur, would later command American forces in the Pacific during World War II.
