The **Jewish Student Union (JSU)** is a dynamic organization dedicated to fostering Jewish identity and community among Jewish teens attending public high schools across North America. Founded in 2002 with just four clubs in Los Angeles, JSU has rapidly expanded to operate over 400 Jewish culture clubs on public high school campuses, engaging more than 20,000 teenagers annually[1]. Its core mission is straightforward: to encourage Jewish teens to *do something Jewish* by providing accessible, fun, and meaningful Jewish experiences within their everyday school environments[1]. JSU clubs typically meet during lunch or before/after school, offering a welcoming space for Jewish students to gather. These meetings include a variety of programs such as guest speakers from diverse Jewish organizations, interactive discussions on relevant cultural and social topics, and activities that build Jewish pride and connection to Israel. The clubs emphasize social bonding, often providing kosher snacks like pizza, doughnuts, and holiday foods to complement the programs[1]. Beyond regular meetings, JSU sponsors a wide array of activities including retreats, citywide holiday celebrations, community service projects, ski trips, and Shabbat dinners, enriching Jewish life and community among youth outside the school setting[1]. JSU is notable not only for its scale but also for its inclusive and grassroots approach, aiming to reach all types of Jewish teens in public schools, a population often underserved by traditional Jewish institutions. It emphasizes creating a safe, fun, and culturally rich environment where Jewish teens can explore their heritage, form friendships, and build resilience against rising antisemitism[6]. Though smaller in scope and younger than Hillel International—the world's largest Jewish campus organization serving college students—JSU complements the Jewish educational ecosystem by focusing specifically on high school students, providing early-stage identity formation and community-building opportunities before college[1][2][4]. Its success lies in its growth trajectory, innovative programming, and its ability to meet Jewish teens where they are, making Jewish life relevan
