The Grozny Synagogue (Russian: Ашкеназская синагога; Hebrew: בית כנסת גרוזני) was an Ashkenazi Orthodox Jewish synagogue located in the city of Grozny in the Chechen Republic, North Caucasus, Russia.

In 1929, the synagogue was closed, later rebuilt, and repurposed for secular uses.

In the mid-19th century, a settlement of Mountain Jews, likely migrated from Dagestan, appeared in Grozny on the right bank of the Sunzha River.

[2][3] It was replaced by a large domed synagogue, built of brick, located between the Persian mosque and the Mitnikov bathhouse.

[4] In the early 1930s, during the period of religious persecution, the Soviet government closed the synagogue.
