Hillel HaLevi Malisov of Paritch, a levite by birth, commonly known as Reb Hillel Paritcher (1795-1864) was a famous Orthodox Jewish Chabad Rabbi born in Khmilnyk, Ukraine. Specifically, he served as a Mashpia (Hasidic mentor) and communal rabbi in the towns of Paritch (Parwich Parichi), near Minsk, Russia, and Bobroisk, Belarus. He was considered exceptional in his scholarship and piety, and is referred to as a Tzadik, and even as a "half Rebbe."

He was born in Khmilnyk, Ukraine, but grew up in Chemtz ( which is in the vicinity of Minsk). Although he was originally a disciple of Rabbi Mordechai of Chernobyl, he became a disciple of Rabbi Shneur Zalman of Liadi (though he never saw him) after learning in a “hidden” Tanya without the title page. In 1815 he began to travel regularly to Rabbi Dovber of Lubavitch and, after the latter’s passing, became a disciple of Rabbi Dovber's successor, Rabbi Menachem Mendel.
