The Elverum Authorization (Norwegian: Elverumsfullmakten) allowed the Norwegian executive branch to temporarily and legitimately assert absolute authority given that parliament was no longer able to convene in ordinary session in Oslo. The action was approved unanimously by the Parliament of Norway (the Storting) on 9 April 1940, in the town of Elverum, in Norway, after the Norwegian royal family, executive branch, and parliament had evacuated Oslo to evade capture by German troops in the course of Operation Weserübung during World War II.
