The Congregation B'nai Jacob (transliterated from Hebrew as "Sons of Jacob") is a Conservative Jewish congregation and synagogue located at 75 Rimmon Road, in Woodbridge, Connecticut, in the United States.
Congregation B'nai Jacob was established in New Haven in 1882. Founded by Orthodox Ashkenazi Jewish refugees fleeing pogroms in the Russian Empire, it was first on Temple Street in New Haven, then moved to George Street in 1912, in a building completed in the Moorish Revival style.
In 1961, the congregation moved to Woodbridge, following the construction of a new synagogue designed by Fritz Nathan and Bertram Bassuk in the Modernist style. A defining feature of the sanctuary is an impressive display of stained-glass windows by Jean-Jacques Duval.
Rona Shapiro was appointed the congregation's first female rabbi in 2013.
