Haim Herman Cohn (Hebrew: חיים הרמן כהן; 11 March 1911 – 10 April 2002) was an Israeli jurist and politician.

[3] As Attorney General, he decided to indict Malchiel Gruenwald, starting the Rudolf Kastner trial[5] and decided to ignore the (British based) law "and refrained from pressing charges on the conduct of homosexual relations between consenting adults".

[3] In addition to his civil service, he was also a visiting lecturer in the Tel Aviv University (from 1956 to 1969) and Hebrew University of Jerusalem (from 1954 to 1976) law schools, a representative of Israel in the United Nations Human Rights Council and a member of the International Court of Justice in The Hague.

[8] Cohn's relationship with Orthodox Judaism was generally perceived as strained, however, in at least one instance, in 1975, Cohn was honored by Rabbi Menachem Mendel Schneerson of the Chabad-Lubavitch Hasidic dynasty with participation in the annual Simchat Torah ceremonies.

[1] President of the Supreme Court Aharon Barak cited him as one of the founders of Israeli law.
