Sarah Rebecca Rachel Leah Horowitz (1715–1795), known as Leah Horowitz, was a rabbinic and kabbalistic scholar, who wrote in Yiddish. She was the author of Tkhinne imohes (Supplication of the Matriarchs). She lived in Bolechów, Poland. Life Horowitz was the daughter of Jacob Yokl ben Meir Ha-Levi Horowitz (1680–1755) and Reyzel bat Heshl. Her father was a member of the famed kloiz of Brody. Horowitz was one of some seven children. Three of her brothers were rabbis, of whom the most eminent was Isaac (known as "Itsikl Hamburger", 1715–1767), rabbi of Hamburg, Altona, and Wandsbek. There was also a sister, named Pessil. There is some doubt about the identity of another brother and sister.

In an era when many women did not learn to read, and those who did rarely learned more than the rudiments of Hebrew, Horowitz studied the Talmud with commentaries and also read some kabbalistic works. The memoirist Ber of Bolechów reports that when he was a boy of twelve, Leah helped him prepare for his Talmud lesson with her brother, the rabbi Mordecai. "She would begin to recite the words of Talmud or Rashi by heart, in clear language, explaining it well as it was written there, and I learned from her words. And when the rabbi awoke from his sleep, I knew how to explain the passage in the Talmud to him properly." In the same passage, Ber refers to her as "the learned and famous Mistress Leah, of blessed memory". Other authors also knew of her reputation for learning. The anonymous work Sefer Ozar Sihot Hakhamim describes her as "a great
