The International Organization of Journalists (IOJ, French: Organisation internationale des journalistes) was an international press workers' organization based in Prague, Czechoslovakia, during the Cold War. It was one of dozens of front organizations launched by the Soviet Union in the late 1940s and early 1950s. It was controlled in Prague by the Central Committee of the Czechoslovak Communist Party, with the assistance of KGB agents. It was described by the U.S. Central Intelligence Agency as "an instrumentality of Soviet propaganda".
