Ungdomsfylking and NSUF, was the Norwegian fascist party Nasjonal Samling's organization for children and young people between the ages of 10 and 18 before and during the Second World War from 1933 to liberation in the spring of 1945.

Nasjonal Samling (NS) sprung from Nordisk Folkereisning, a fascist group founded in Oslo in 1931, and was established as a political party through an announcement in Tidens Tegn on 17 May 1933.

Then the law student Rolf Jørgen Fuglesang, who later became NS minister during the war, became national leader of the National Youth Movement, an organization that later changed its name to Nasjonal Samling Youth Wing.

The chiefs of staff for the Unghirden and the Guttehirden represented the organization in the Nasjonal Samling's national leadership.

The organization was built according to roughly the same military pattern as the Hirden, the NS's "elite troops", with a team, troop, platoon, county and regiment.This article about politics in Norway is a stub.
