Samuel Solomon Cohon was an American rabbi and Chair of Theology at Hebrew Union College, a leader of American Reform Judaism in the mid-20th century.

The Union for Reform Judaism (URJ), formerly known as the Union of American Hebrew Congregations (UAHC) until 2003, founded in 1873 by Rabbi Isaac Mayer Wise, is the congregational arm of Reform Judaism in North America. The other two arms established by Rabbi Wise are the Hebrew Union College-Jewish Institute of Religion and the Central Conference of American Rabbis. The current president of the URJ is Rabbi Rick Jacobs.
