Trondheim Airport (Norwegian: Trondheim lufthavn; IATA: TRD, ICAO: ENVA), more commonly known as Værnes, is an international airport serving Trondheim and the surrounding areas in Trøndelag county, Norway. The airport is located in Værnes, a village in Stjørdal Municipality which is located 10 nautical miles (19 km; 12 mi) east of Trondheim Municipality. Operated by the state-owned Avinor, it shares facilities with Værnes Air Station of the Royal Norwegian Air Force. In 2018, the airport had 4,441,870 passengers and 58,273 air movements, making it the fourth-busiest in the country. The airport has two terminals; A dates from 1994 and is used for domestic traffic, while B is the renovated former main terminal from 1982, and is used for international traffic. The airport features a main east–west 2,999-metre (9,839 ft) runway, a disused northwest–southeast 1,472-metre (4,829 ft) runway, an integrated railway station and an airport hotel.
The main airlines at the airport are Scandinavian Airlines (SAS), Norwegian Air Shuttle and Widerøe, for all of which Værnes is a focus city. The main route is the service to Oslo, operated by Norwegian, SAS, and Widerøe, which is the fourth-busiest route in Europe and there are also some additional domestic services operated by Airbus A320, Boeing 737, Dash 8 and Embraer E2.

In October 2020, Wizz Air had reported Trondheim and Oslo airports as their new bases in Norway, with daily flights from Trondheim to Oslo, Stavanger, Bodø and Tromsø; however the base in Trondheim was shut down in February 2021, resulting in frequency decrease. Some international services to Copenhagen and Stockholm is provided by SAS and to Amsterdam is provided by KLM. The airport also serves charter services, mainly to the Mediterranean. In total, it connects to 15 domestic and 15 international destinations, as well as 18 charter destinations.
Værnes was taken into use by the Royal Norwegian Army in 1887. The first flight was made in 1914, and aerodrome facilities were gradually installed. The first main installations, including three concrete runways, were built during World War II by the Luftwaffe. After the war, the Air Force Pilot School moved to Værnes, although in 1954 most of the other air force activities for Central Norway were moved to Ørland Main Air Station. Civilian aviation started in 1951, when half a barracks was taken into use as a terminal, with the whole building being utilized from 1958. Jet aircraft started serving Værnes from 1963, and the second terminal opened in 1965. The third (the current international Terminal B) was opened in 1982, and the fourth, Terminal A, was opened in 1994, along with the train station. From 1956 to 2004, Braathens was one of the largest airlines at the airport.
