Knut Ingolf Løfsnes (22 December 1918 – 5 January 1996) was a Norwegian resistance member, politician and lawyer.
At the time of the Namsos Campaign, a part of World War II fighting in 1940, he returned home.
The Allied forces eventually lost the Namsos Campaign, Germany occupied Norway and Løfsnes joined the Norwegian resistance movement.
He was arrested in 1942, was imprisoned in Falstad concentration camp from June to July 1942, was released and fled to Sweden in the same year.
Here he led the mid-Norway department of the clandestine organization XU from the Norwegian legation in Stockholm from 1942 to 1945.
