Talgat Safich Tadzetdinov, better known as Tadzhuddin (Russian: Талгат Сафич Тадзетдинов / Талгат Таджуддин, Tatar: Тәлгать Сафа улы Таҗетдинев, Tälğät Safa ulı Tacetdinev; born 12 October 1948, in Kazan) is a Russian Shaykh al-Islām.

[1] Tadzhuddin is a polarizing figure in Russia due to his public statements, which include for example suggesting that participants of a pride parade should be attacked physically, and more recently, that Russian invasion of Ukraine is a "necessary measure".

[1] In 1992, DUMES was transformed into the Central Spiritual Administration of the Muslims of Russia and the European countries of the CIS; the rank of Grand Mufti was created and bestowed on Talgat Tadzhuddin.

[1][2][3] However, on February 20, 2016, at an expanded meeting of the Presidium of the Central Spiritual Administration of Muslims in Ufa, a decision was made to cancel the farman decree.

[1] Tadzhuddin has at least on one occasion claimed that he is a Bulgarian, arguing that Tatars are the descendants of Volga Bulgaria after it fell during the Mongol invasions.
