The Thousandth Anniversary of Islam Mosque or The Anniversary Mosque (Russian: Мечеть 1000-летия принятия Ислама, Мечеть Юбилейная – Mechet’ 1000-letiya prinyatiya Islama, Mechet’ Yubileynaya) was built in Kazan, Tatarstan, Russia to commemorate the thousandth anniversary of the conversion of the Volga Bulgars in to Islam in 922.

The alternative name of the mosque, and the most commonly used name, is The Mosque Across the Kaban (Russian: Закабанная мечеть, Zakabannaya mechet’; Tatar: Кабан арты мәчете, Qaban artı mäçete, قابان ارتئ مەچئتئ), because most of Kazan's mosques are situated on the other side of the Kaban, where the Tatar community was traditionally located before the October Revolution.

The part where the mosque was situated was inhabited predominantly by the Russian community.

Based on a design by Pechnikov from 1914, the mosque was built from 1924 to 1926 with private donations by Muslims.
