Knut Møyen (19 January 1907 – 20 March 1984) was a Norwegian economist and resistance member.
After the German invasion of Norway in 1940 he participated in the Norwegian Campaign.
His "shadow" Jens Christian Hauge later eventually became the leader of Milorg.
In 1942 he just managed to avoid being caught by the Gestapo, and fled to Sweden and later to the United Kingdom.
A memorial designed by Nils Aas was unveiled in Nordmarka in 1989.
