Herman Stsepanovich Kantoyeu (Belarusian: ?????? ?????????? ???????; born November 27, 1971 in Khabarovsk, Russian SFSR) is a retired amateur Belarusian freestyle wrestler, who competed in the men's featherweight category.
Considered as one of the world's top freestyle wrestlers in his decade, Kantoyeu became a freestyle wrestling champion in the 54-kg division at the 2001 World Wrestling Championships, and later represented his nation Belarus in two editions of the Olympic Games (2000 and 2004).
Kantoyeu was also a member of the Belarusian national wrestling team since the breakup of the Soviet Union, under his personal coach Valentin Murzinkov.
Kantoyeu made his official debut at the 2000 Summer Olympics in Sydney, where he competed in the men's bantamweight category (54 kg).
He pinned Cuba's Wilfredo GarcÃa on his opening bout, but could not beat Kyrgyzstan's Nurbin Donbaev with a score 2–5 in the prelim pool.
Despite a single loss, Kantoyeu still managed to secure a spot for the quarterfinals because of the most points collected from the elimination round.
Followed by the next morning's session, Kantoyeu delivered a striking effort to edge Kazakhstan's Maulen Mamyrov off the mat in his next match, before falling behind U.S.
wrestler and 1998 world champion Sammie Henson in the semifinals without scoring a single point.
He faced against Greece's Amiran Kardanov in the bronze medal match, but nearly missed out the podium by single point behind his opponent with a score 4–5, finishing only in fourth place.Determined to return again to the wrestling scene, Kantoyeu greatly emerged as a top medal contender at the 2001 World Wrestling Championships in Sofia, Bulgaria, where he beat Iran's Babak Nourzad to take home the gold medal in the men's bantamweight category.
He lost his opening bout to Ukrainian wrestler and 2003 world bronze medalist Oleksandr Zakharuk, but scored a single triumph to subdue Kazakhstan's Baurzhan Orazgaliyev in the prelim pool.
Finishing second in the elimination round and fifteenth overall, Kantoyeu could not deliver a remarkable attempt from Sydney to put him further into the quarterfinals.
