Congregation Beth Israel, Reform synagogue in University City, San Diego, United States

Congregation Beth Israel is a Reform Jewish congregation and synagogue in University City, San Diego. Its campus, dedicated in October 2001, comprises five buildings totaling more than 65,000 square feet on a 3-acre lot purchased in 1993. The congregation is San Diego's largest and oldest Jewish congregation, with over 2,000 members.

Jews arrived in San Diego in 1850 and held High Holiday services yearly; in 1861 Marcus Schiller led the organization of a congregation called Adath Yeshurun, formally incorporated as Beth Israel in early 1887. Its first wooden synagogue, built in 1889 at Second Avenue and Beech Street, still stands in Heritage Park near Old Town; services began there on September 25, 1889, and the congregation used it until 1926. Beth Israel bought a 3-acre lot in University City in 1993 and dedicated its current campus there in October 2001.

The name Beth Israel means "House of Israel" in Hebrew. The congregation is led by Senior Rabbi Jason Nevarez, Rabbi Cantor Jeremy Gimbel, Assistant Rabbi Elana Ackerman-Hirsch and Rabbi Arlene Bernstein, Cantor Emerita; Michael Berk became Rabbi Emeritus in June 2019. Members have included Louis Rose, a pioneer developer of San Diego, and Alan Bersin, a former US Attorney and federal border official.

The facility is accessible to visitors during the day, especially during Shabbat services and other regular events. It is wise to check in advance when public gatherings happen, as access may be restricted during private functions.

The congregation's first synagogue, a wooden building erected in 1889 at Second Avenue and Beech Street, still stands in Heritage Park beside Old Town San Diego State Historic Park; services were first held there on September 25, 1889, and the congregation used it until 1926.
