Tulsa International Airport (IATA: TUL, ICAO: KTUL, FAA LID: TUL) is a civil-military airport five miles (8 km) northeast of downtown Tulsa, in Tulsa County, Oklahoma, United States. It was named Tulsa Municipal Airport when the city acquired it in 1929; it got its present name in 1963. While Tulsa International Airport only serves domestic destinations, it is still an international airport since it has customs and border patrol facilities.

The 138th Fighter Wing of the Oklahoma Air National Guard is based at the co-located Tulsa Air National Guard Base. The airport is the global maintenance headquarters for American Airlines.

During World War II Air Force Plant No. 3 was built on the southeast side of the airport, and Douglas Aircraft manufactured several types of aircraft there. After the war this facility was used by Douglas (later McDonnell Douglas) and Rockwell International (later Boeing) for aircraft manufacturing, modification, repair, and research. Spirit AeroSystems currently builds commercial airline parts for Boeing aircraft in part of the building and IC Bus Corporation assembles school buses in the other part. Spirit AeroSystems also builds Boeing wing and floor beam parts and Gulfstream wing parts in a facility on the east side of the airport, just north of runway 26.

The Tulsa Air and Space Museum is on the northwest side of the airport.
