Nota Schiller (Hebrew: נטע שילר, born 1937) is an Orthodox Jewish rabbi and rosh yeshiva of Yeshivat Ohr Somayach, Jerusalem.

He is an influential figure in the baal teshuva movement,[1] having guided generations of students with little or no Jewish background to master the classical rabbinical texts[2] and embrace an Orthodox lifestyle.

In 1972, Rabbis Noah Weinberg, Mendel Weinbach, Nota Schiller, and Yaakov Rosenberg founded Shma Yisrael Yeshiva to teach young Jewish men with little or no background in Jewish studies.

Shma Yisrael subsequently changed its name to Ohr Somayach, after the commentary on the Mishneh Torah written by Rabbi Meir Simcha of Dvinsk, the Ohr Somayach, in response to critics who contended that the name belonged to the entire Jewish people, not just one institution.

[7] Schiller was the driving force behind the development of Ohr Somayach International, which has opened yeshivas and learning branches in the United States, Canada, United Kingdom, South Africa, and Australia.
