Yevgeny Aleksandrovich Tuchkov (Russian Евгений Александрович Тучков; 1892, Suzdal, Vladimir Governorate – 15 April, 1957, Moscow) was a Soviet state security officer and the head of the anti-religious department of the Soviet OGPU.
He finished four years of primary education after which he worked as a baker and also in a leather shop.
From 1922 to 1929 Tuchkov headed the sixth secret department of the OGPU which targeted the Russian Orthodox Church during the 1920s.
During this period, Tuchkov orchestrated a campaign of persecution against the church which included the mass arrests and executions of clergy.
He had also begun supporting the liberal and modernist Living Church movement, seeking to make it a replacement for traditional Russian Orthodoxy.
