Avinor AS is a state-owned limited company that operates most of the civil airports in Norway.

Avinor was created on 1 January 2003, by the privatization of the Norwegian Civil Aviation Administration known as Luftfartsverket.

On 1 July 1947, the Norwegian Ministry of Transport and Communication created the Aviation Directorate (Luftfartsdirektoratet) to take over the responsibility for the civilian airports in Norway.

Until then the Norwegian Ministry of Defence was responsible for operating airports, including the civilian ones.

The first director was Einar Bøe (1947–1964), followed by Erik Willoch (1964–1989), Ove Liavaag (1989–2000), Randi Flesland (2000–2005), Sverre Quale (2006–2010),[2] Dag Falk-Petersen (2011–2021) and Abraham Foss (2021–).
