Temple B'Nai Israel is a deconsecrated synagogue located in Olean, Cattaraugus County, New York, in the United States.

B'Nai Israel continued to hold its twice-monthly regular services at the time, but it was said to be in danger of closing within a decade due to the ongoing exodus of young people from the Olean region.

[3] B'Nai Israel's synagogue building from 1929 to 2019 was a three- to four-story tall, light brown brick structure with terra cotta decorative details.

[2] The front facade features a massive arched terra cotta portal encircling a large, round stained glass window.

[1] In July 2019, the synagogue announced that it would be closing after Yom Kippur services that fall as it sought to rent a smaller facility.
