Yaakov Yitzchak HaLevi Horowitz (Hebrew: יעקב יצחק הלוי הורוביץ), known as "the Seer of Lublin" (החוזה מלובלין‎), ha-Chozeh MiLublin; (c. 1745 - August 15, 1815)[1] was a Hasidic rebbe from Poland.

[2][3] A leading figure in the early Hasidic movement, he became known as the "seer" or "visionary" due to his purported ability to gaze across great distance by supernatural means.

[5] Among his disciples were such Hasidic luminaries as Yaakov Yitzchak Rabinowicz ("the Holy Jew"), Simcha Bunim of Peshischa, Meir of Apta, David of Lelov, Moshe Teitelbaum, Tzvi Elimelech of Dinov, Naftali Zvi of Ropshitz, and Shalom Rokeach of Belz.

[8] Lately the Lublin Organization in New York[9] made an attempt to restitute the property in order to rebuild the synagogue in remembrance of Rabbi Horowitz, but their efforts were unsuccessful.

His writings are contained in four books:[12][13] In a compilation of these works, entitled Torat HaChozeh MiLublin, his commentaries are arranged alphabetically according to topics and according to the weekly Torah portion.
