Jonathan I. Rosenblatt (born August 31, 1956) is an American Modern Orthodox rabbi, teacher, lecturer, and counselor.
A native of Baltimore, Rabbi Rosenblatt has served for more than thirty years as the Senior Rabbi of the Riverdale Jewish Center in The Bronx, New York. Under his leadership the RJC has become the largest "teaching synagogue" in the country, through its Rabbinic and Pre-rabbinic internship programs. Rabbi Rosenblatt is known for his work in bridging the gaps that divide Orthodox, Conservative, Reform and secular Jews, and for actively supporting the Oslo peace process in the Middle East. He has lectured widely in the United States, the United Kingdom, South Africa, and Israel and is often quoted on topics of concern to the Jewish community.
Rabbi Rosenblatt earned a BA and MA from Johns Hopkins University in Comparative Literature and a PhD from Columbia University in Modern British Literature. He studied in Israel at Yeshivat Har Etzion and was ordained by the Rabbi Isaac Elchanan Theological Seminary of Yeshiva University.
Rabbi Rosenblatt is the great-grandson of celebrated cantor Yossele Rosenblatt, and the grandson of Rabbi Samuel Rosenblatt, founding rabbi of the Beth Tefiloh congregation in Baltimore and pioneer of the Beth Tfiloh Dahan Community School. Rabbi Rosenblatt and his wife Tzipporah Twersky Rosenblatt, an attorney, have four children: Judah, Tonya, Samuel, and Rivka.
