Johan Borgen (1902 – 1979) was a Norwegian author, journalist and critic. Under the pseudonym of Mumle Gåsegg (Mumble Goose-egg) he wrote shorter articles in the newspaper Dagbladet, particularly during World War II. His articles were ironic and derogatory of the Nazi government, and he kept this up for a long time before being found out. In the end though, he was caught and sent to the prison camp Grini. His best known work is the novel Lillelord (1955). Borgen was editor of the literary magazine Vinduet ("The Window") 1954-1959.
