Hubertus Czernin (born Hubertus Alexander Felix Franz Maria Czernin von und zu Chudenitz; 17 January 1956 – 10 June 2006) was an Austrian investigative journalist.

From the mid-1980s to his untimely death in 2006, he was one of the most important journalists in the German-speaking world and a key figure in Austria. He is most known in Austria for helping to expose the child sex abuse scandal of Archbishop of Vienna Groer as well as the Nazi past of former United Nations Secretary-General and Austrian President Kurt Waldheim, and is most known in the United States for being instrumental in the eventual restitution of Gustav Klimt's Adele Bloch-Bauer I - as depicted in the movie Woman in Gold - to its rightful Jewish heirs.
