Jasenovac – istina is a 2016 revisionist documentary film by the Croatian filmmaker Jakov Sedlar. The film contends that the extent of the Holocaust in Croatia and the World War II-era genocide of the country's Serb population was exaggerated through post-war communist propaganda. It focuses primarily on Jasenovac, a concentration camp run by Croatia's wartime fascist Ustaše government where an estimated 100,000 are believed to have perished, and suggests that the actual death toll never exceeded 18,000. The film also argues that Jasenovac continued being used as a concentration camp by Yugoslavia's communist authorities well after World War II, and that more inmates perished when it was run by the communists than when it was run by the Ustaše.
