Brit HaKanaim (Hebrew: בְּרִית הַקַנַאִים, lit. Covenant of the Zealots) was a radical Jewish underground organization which operated in Israel between 1950 and 1953, in opposition to the widespread trend of secularization in the country. The group was made up of several dozens of boys and girls, who were students at the Porat Yosef Yeshiva in Jerusalem. The underground had more than 35 members at its peak.
