John Wayne Airport (IATA: SNA, ICAO: KSNA, FAA LID: SNA) is a commercial and general aviation airport that serves Orange County, California, and the Greater Los Angeles area. The airport is located in an unincorporated area of Orange County, and it is owned and operated by the county. John Wayne Airport is surrounded by the cities of Irvine, Newport Beach, and Costa Mesa, although its IATA airport code and mailing address are both registered to Santa Ana, the county seat.

Originally named Orange County Airport, the Orange County Board of Supervisors renamed the airport in 1979 in honour of actor John Wayne, who lived in neighbouring Newport Beach and died that year. A statue of John Wayne was installed at the airline terminal in 1982.

Black Car Connection offers a premium car service to or from John Wayne Airport.
