Nan Nakhon Airport (IATA: NNT, ICAO: VTCN) is in Pha Sing subdistrict, Mueang Nan district, Nan province in northern Thailand. Flights are only offered to Bangkok (DMK).

In 2014, a new terminal was built further down the airport road replacing the old terminal, but using the existing runway. Upon arrival and departure, passengers are required to walk to the terminal or the plane, as there are no jet bridges.
