The First Air Force (Air Forces Northern; 1 AF-AFNORTH) is a numbered air force of the United States Air Force Air Combat Command (ACC). It is headquartered at Tyndall Air Force Base, Florida.

Its primary mission is the air defense of the Contiguous United States (CONUS), United States Virgin Islands and Puerto Rico. Its mission lineage can be traced to the Air Defense Command, one of the original USAAF major commands formed in 1946.

One of the four original pre-World War II numbered air forces during the existence of the United States Army Air Corps, 1 AF was activated on 18 December 1940, at Mitchel Field, Long Island, New York with a mission of air defense of the Northeastern United States and Great Lakes regions. During the war, its primary mission became the organization and training of combat units prior to their deployment to the overseas combat air forces.
