Eliyahu Stefansky (; born November 21, 1972) is the founder of Mercaz Daf Yomi in Ramat Beit Shemesh, Israel, whose daf yomi broadcasts are the most popular shiurim in the world.

Early life and education Stefansky was born in Lakewood Township, New Jersey, to Rabbi Yaakov and Rebbetzin Ruthie Stefansky. He is the oldest of seven children. He grew up in Far Rockaway, Queens, where he attended Yeshiva Darchei Torah. In the fifth grade, his family made aliyah, moving to Bnei Brak, Israel, and Stefansky studied at the Ponevezh Yeshiva under Michel Yehuda Lefkowitz. After three years, the Stefanskys returned to the United States, and Stefansky attended Yeshiva Gedola of Passaic. Stefansky returned to Israel to study at the Mir Yeshiva.

Stefansky began his career in Chicago as an electrician, plumber, and carpenter to enter into real estate. On the side, he maintained a catering business, working about 100 weddings per year. At one wedding in 2005, a real estate broker in Indianapolis offered Stefansky the option to purchase 2,000 apartments. This became PrimeQuest.
