Oregon World War II Army Airfields were the airfields built or repurposed during World War II for training pilots and aircrews of United States Army Air Forces (USAAF) fighters and bombers in Oregon.
Most of these airfields were under the command of Second Air Force or the Army Air Forces Training Command (AAFTC) (predecessor of the current-day United States Air Force Air Education and Training Command). However the other USAAF support commands (Air Technical Service Command (ATSC); Air Transport Command (ATC) or Troop Carrier Command) commanded a significant number of airfields in a support roles.
It is still possible to find remnants of these wartime airfields. Many were converted into municipal airports, though some were returned to agriculture and several were retained as United States Air Force installations and were front-line bases during the Cold War. Hundreds of the temporary buildings that were used survive today, and are being used for other purposes.
