The International Conference to Review the Global Vision of the Holocaust was a two-day conference in Tehran, Iran that opened on December 11, 2006. Iranian foreign minister Manouchehr Mottaki said the conference sought "neither to deny nor prove the Holocaust... [but] to provide an appropriate scientific atmosphere for scholars to offer their opinions in freedom about a historical issue". Participants included David Duke, Moshe Aryeh Friedman, Robert Faurisson, Fredrick Töben, Richard Krege, Michèle Renouf, Ahmed Rami and Yisroel Dovid Weiss of Neturei Karta.

The conference was described by international media outlets as a "Holocaust denial conference" or a "meeting of Holocaust deniers."The conference provoked strong criticism. The Vatican condemned it, the US administration of President George W. Bush called it an "affront to the entire civilized world," and British Prime Minister Tony Blair described it as "shocking beyond belief." Historians of the Holocaust attended a separate conference in Berlin organized in protest against the assembly in Iran, calling it "an attempt to cloak anti-Semitism in scholarly language."
