Itamar Ben Gvir (Hebrew: איתמר בן-גביר‎; born 1976) is a Knesset aide to MK Rabbi Dr. Michael Ben-Ari and a spokesman for the Jewish National Front Party, a right-wing Jewish party in Israel.

Among its goals are the transfer of all Non-Jews in Israel who object to Israel as a Jewish state. A member of the Kach Party since the age of 14, Ben Gvir denies that there is a such thing as current membership, citing government harassment as impeding that. Nevertheless, he and his colleagues, mainly the former Kach leaders Noam Federman and Baruch Marzel (both, like Ben-Gvir, convited criminals), remain the students of their teacher and leader, Kach founder and ideologue Rabbi Meir Kahane.

Since the 1990 assassination of Rabbi Kahane in New York, Marzel has been the de facto political leader of the former Kach activists. Today, Ben-Gvir is the spokesman and youth organizer and Federman is an aggressive activist in the field and a leader of The Hilltop Youth. Ben Gvir has often been accused of incitement for the fierce verbal attacks he throws against political figures, almost always calling them in some way traitors. Ben Gvir is a fixture of settler violence against Palestinians living near Jewish settlements in the occupied territories.
