Vasili Nikitich Mitrokhin (Russian: Василий Никитич Митрохин) (March 3, 1922–January 23, 2004) was a Major and senior archivist for the Soviet Union's foreign intelligence service, the First Chief Directorate of the KGB, and co-author with Christopher Andrew of The Mitrokhin Archive: The KGB in Europe and the West, a massive account of Soviet intelligence operations based on copies of material from the archive. Work on the second volume, The Mitrokhin Archive II: The KGB in the World, was completed by Andrew in 2005 after Mitrokhin's death.
