Lincoln Airport (IATA: LNK, ICAO: KLNK, FAA LID: LNK; formerly Lincoln Municipal Airport) is a joint public/military airport five miles (8.0 km) northwest of downtown Lincoln, the state capital, in Lancaster County, Nebraska, United States. It is owned by the Lincoln Airport Authority and is the second-largest airport in Nebraska. It is included in the Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2023–2027 in which it is categorized as a non-hub primary commercial service facility. It has four gates with jetways, to be, as of February 2022, expanded to six.

The 12,901-foot (3,932 m) primary runway was a designated emergency landing site for the Space Shuttle, although it was never used as such. The runway can handle heavy military aircraft including the C-5 Galaxy and the Boeing E-4. The airport is also the home of Lincoln Air National Guard Base, an installation for the KC-135R Stratotanker aircraft operated by the 155th Air Refueling Wing (155 ARW) of the Nebraska Air National Guard. Airliners on charter flights by visiting college athletic teams which play the Nebraska Cornhuskers also utilize Lincoln Airport as a primary destination, although many football teams fly into Omaha's Eppley Airfield, since they lodge in Omaha the night before a game due to lack of available hotel space in Lincoln, then depart from Lincoln immediately after the game. The airport is home to Duncan Aviation, a family-owned aircraft maintenance and refurbishing company. Duncan Aviation has hangars on the east side of the airport and parts storage on the west side.
