Yisroel Dovid Weiss (born 1956) is a Haredi Jew, activist, and spokesman for a minority branch of Neturei Karta, a Haredi anti-Zionist group. Residing in Monsey, New York, he believes that Jews should peacefully oppose the existence of the Israeli state: “It would be forbidden for us to have a State, even if it would be in a land that is desolate and uninhabited.” He represents less than 500 people, and Neturei Karta’s extreme views, created around 100 years ago, are rejected by the vast majority of Orthodox Jews worldwide.

Weiss was criticized in 2006 for his participation in the International Conference to Review the Global Vision of the Holocaust, widely considered to be an event promoting Holocaust denial internationally. He was placed under cherem by Yonah Metzger, the Ashkenazi Chief Rabbi of Israel, and the anti-Zionist Satmar dynasty also urged its members to shun him and others who participated in the conference. Weiss claimed to be speaking as “the voice of the people who died in the Holocaust”.
