Geir Kjetsaa (2 June 1937 in Oslo – 2 June 2008) was a Norwegian professor in Russian literary history at the University of Oslo, translator of Russian literature, and author of several biographies of classical Russian writers.

He was the son of Thorleif Kjetsaa (1907–69) and Marit Elen Hansen (1912–82).

[2] A 1984 monograph by Kjetsaa and others used statistical analyses which support the view that Mikhail Sholokhov was likely the true author of And Quiet Flows the Don - defending the Soviet writer against persistent allegations of plagiarizing.

Among his other biographies were works on Yevgeny Baratynsky, Fyodor Dostoevsky, Nikolai Gogol, Maxim Gorky, Leo Tolstoy and Anton Chekhov.
