Sinai Temple (Hebrew: סִינַי) is a Reform Jewish synagogue located at 1100 Dickinson Street, in Springfield, Massachusetts, in the United States.

The congregation's first rabbi, David M. Eichhorn, was hired in 1932 and let go just two years later due to financial difficulty brought on by the Great Depression,[3] though he went on to become a prominent American rabbi and authority on interfaith marriage and conversion for the Reform movement.

The congregation began meeting at a mansion at 188 Sumner Avenue in Springfield in 1932, which was used as a synagogue until the late 1940s.

[4] In 1949 Sinai broke ground on a new location at 1100 Dickinson Street, near the Longmeadow border, which was completed in 1950.

[1] Notably, Sinai has had two long-tenured rabbis: Herman E. Snyder (1947–1970) and Mark D. Shapiro (1988–2016).
