Älvsbyn Airfield (ICAO: ESUV) is a small general aviation facility located in Älvsbyn, a municipality in Norrbotten County in northern Sweden. The airfield primarily serves private and light aircraft operations, supporting local transportation needs in a sparsely populated region of the Swedish Arctic interior. The airfield does not operate scheduled commercial airline services and lacks the infrastructure of larger regional airports. It serves as a convenient access point for the surrounding area, which is otherwise reliant on road travel or the larger airports at Luleå and Arvidsjaur for commercial connections.
