Viktor Antonovich Avdyushko (Russian: Виктор Антонович Авдюшко; January 11, 1925 – November 19, 1975) was a Soviet actor and a People's Artist of the Russian SFSR.
Avdyushko was born to a father who worked as a weight inspector in the Kiyevsky Rail Terminal and to a housewife mother, who also raised one older daughter. Initially a student in the Moscow Aviation Institute, he left it and was admitted into the All-Union State Institute of Cinematography, where he studied under Yuli Raizman. He graduated from the academy in 1949, and joined the regular cast of the Mosfilm studio.
He made his debut on screen with a minor role in Sergei Gerasimov's 1948 film The Young Guard. Avdyushko continued to play supporting characters during the following years, in pictures such as Cossacks of the Kuban and Hostile Whirlwinds. He was given his first major appearance in the 1955 Heroes of Shipka, when he depicted the Russian soldier Osnobishin.
In 1957, Avdyushko was cast for the leading role in Mikhail Schweitzer's Tight Knot, adapted from a story by Vladimir Tendryakov. He portrayed Pavel Mansurov, an idealist Kolkhoz general secretary who is corrupted by the power of his office. The film had to be heavily censured in order to be released, and its title was changed to Sasha Comes to Life. The full version was only released in 1988.
