Yevgeny Aleksandrovich Tuchkov (in Russian Евгений Александрович Тучков) (1892–1957) was the head of the anti-religious arm of the Soviet OGPU.
Tuchkov was born in 1892 in the village of Teliakovo near Suzdal. He finished four years of primary education after which he worked as a baker and also in a leather shop. He then served in the Russian Imperial Army as a secretary.
During this period, Tuchkov orchestrated a campaign of persecution against the church which included the mass arrests and executions of clergy. He personally led the questioning of Patriarch Tikhon. He had also begun supporting the liberal and modernist Living Church movement, seeking to make it a replacement for traditional Russian Orthodoxy.
In 1928, Tuchkov enrolled in Moscow State University but dropped out a year later. In 1939, Tuchkov was fired from the NKVD, whereupon he began working as a lecturer for the society "Knowledge". He died in early 1957.
