Viktor Ivanovich Mednov (Russian: Виктор Иванович Меднов, 27 November 1927 – 22 June 2009) was a Russian boxer from the Soviet Union who won a silver medal in the light welterweight division at the 1952 Olympics. He had a difficult second bout with Francisc Ambrus of Romania, with Mednov prevailing when the referee stopped the bout due to bad cuts sustained by both opponents. Mednov had a break in the semifinal, as Erkki Mallenius withdrew with a hand injury. In the final he was defeated by Chuck Adkins in a 2–1 decision. This was the first boxing match between boxers from the United States and the Soviet Union.
Mednov was known for his strength and power – he could hold the Azaryan Cross on gymnastic rings and punched the bags in training so viciously that his hands were bleeding despite ample protection (elastic bandages and full-size competition gloves). In retirement he worked as a boxing coach for his sports society Trudovye Rezervy and painted landscapes as a hobby.
