Rabbi Noach Weinberg (1930–2009), also known as Noah Weinberg, was a prominent American-Israeli Orthodox rabbi and a pioneering figure in modern Orthodox Jewish outreach to secular and unaffiliated Jews. He was the founder of Aish HaTorah in Jerusalem in 1974—an innovative yeshiva and international Orthodox Jewish outreach organization and educational network designed to attract and educate non-observant Jews through intellectual, experiential, and media initiatives. Born in Baltimore, Maryland, he grew up in a religious Jewish family and received his rabbinic ordination from Yeshiva University in 1953. Initially serving as a rabbi in the United States, he became disillusioned with the limited impact of traditional synagogue life on the broader Jewish community and immigrated to Israel in the early 1970s. As founder and long-time dean, he led Aish HaTorah until his death on February 5, 2009, during which time it grew into a global network with branches worldwide, influencing thousands to embrace Torah observance and strengthen Jewish identity amid assimilation.

Weinberg was renowned for his charismatic teaching style and unwavering commitment to "saving souls" by inspiring followers to embrace Jewish observance. He developed a unique outreach methodology that combined rational arguments for faith with emotional appeals, often addressing feelings of guilt and inadequacy to motivate action. Despite early failures in previous ventures, such as unsuccessful outreach attempts in the U.S., he persisted, building Aish HaTorah into a powerhouse that touched millions. His impact extended beyond education; he was a key influencer in the baal teshuva movement, encouraging secular Jews to return to religious practice, and his work fostered international networks of Jewish activists and educators, shaping modern Orthodox outreach strategies.

Personally, he was married to Rivkie Weinberg, and their son, Rabbi Shraga Weinberg, succeeded him as dean of Aish HaTorah, continuing his legacy of influence in Jewish education and outreach. He passed away on February 5, 2009, leaving an enduring legacy as the "Gentle Giant" of Jewish outreach, with Aish HaTorah remaining a vital institution for Jewish renewal.
