Sedona Airport (IATA: SDX, ICAO: KSEZ, FAA LID: SEZ) is a non-towered airport located 2 miles (1.7 nmi; 3.2 km) southwest of the central business district of Sedona, a city in Yavapai County, Arizona, United States. The airport covers 220 acres (89 ha) and has one runway and one helipad.

Although most U.S. airports use the same three-letter location identifier for the FAA and IATA, Sedona Airport is assigned SEZ by the FAA and SDX by the IATA (which assigned SEZ to Seychelles International Airport in Mahé, Seychelles).

The airport is located on top of a high mesa overlooking a major portion of the city; it has been termed a tabletop runway. It is not uncommon for tourists or locals driving around downtown Sedona to see an approaching airplane fly overhead and then suddenly disappear into the mountains without ever appearing to land. The airport is also located very close to the Red Rocks of Sedona.

The airport is well known as being the location of the flying lessons on the ground and in the air in Microsoft Flight Simulator, where it is also one of the handcrafted airports, giving real-life detail of the taxiways and runway.
