Salina Regional Airport (IATA: SLN, ICAO: KSLN, FAA LID: SLN), formerly Salina Municipal Airport, is located in Salina, Kansas, United States. The airport is owned by the Salina Airport Authority. It is used for general aviation, and has service by one passenger airline, SkyWest Airlines (operating as United Express), which is subsidized by the Essential Air Service program.

Salina Regional Airport is the home of K-State Salina and its Department of Aviation, which offers Professional Pilot degrees along with several other degrees in the field of aviation.

The airport is on the site of the former Schilling Air Force Base (previously Smoky Hill Air Force Base and Smoky Hill Army Airfield).

The construction of military airfields after the Pearl Harbor Attack that caused the entry of the United States into World War II resulted in the construction of the Smoky Hill Army Airfield (AAF) on 2,600 acres (1,052 ha), southwest of Salina, Kansas. The first unit associated with the airfield was the 376th Base Headquarters and Air Base Squadron, whose engineers first laid out the base in April 1942. Construction began in May 1942 with the aid of nearly 7,000 workers. The airfield was activated on September 1, 1942, and was assigned to the II Bomber Command, Second Air Force.

Enough construction was completed that the 376th moved into facilities on September 10. The first aircraft to arrive, Boeing B-17 Flying Fortresses, arrived later that month and were assigned to the 346th Bombardment Group. The mission of Smoky Hill AAF was that of a Second Phase Heavy Bomber Operational Training Unit (OTU). In the second phase of training, combat groups formed in the first phase focused on the teamwork of the full combat crew, such as bombing, gunnery, and instrument flight missions. Upon completion, the groups moved on to the third phase, the final level of training before overseas deployment to the combat theaters.

In April 1943, the 49th Aviation Squadron arrived at Smoky Hill; the all-African American unit included mechanics, electricians, and aircraft handlers but no pilots. The 366th was joined by the 400th Bombardment Group in the training mission at Smoky Hill AAF on July 31, 1943. The 366th concentrated on B-17 Flying Fortress training; the 400th on B-24 Liberator training.

On March 21, 1946, as the USAAF underwent significant restructuring, the airfield was transferred to the Fifteenth Air Force, then part of the Strategic Air Command. Then in January 1948, following the formation of the Air Force, the airfield was renamed Smoky Hill Air Force Base.

As postwar budgets declined, the base was eventually closed and turned over to the Air Materiel Command late in 1949.
