Arvidsjaur Airport (IATA: AJR, ICAO: ESNX) is a small regional airport located in Arvidsjaur, a municipality in Norrbotten County in northern Sweden. It serves as a gateway to Swedish Lapland, facilitating both passenger travel and charter operations in a remote Arctic environment. The airport is particularly notable for its role in winter automotive testing, as the Arvidsjaur region is a major hub for cold-weather vehicle testing by European car manufacturers. This brings significant seasonal traffic and charter flights to the area between November and March. Operations are modest in scale, with limited scheduled services connecting Arvidsjaur to Stockholm. The airport is owned and operated by the Swedish Civil Aviation Administration (Swedavia or a regional entity), and serves a relatively small local population supplemented by automotive industry visitors.
