Men's semi-contact at WAKO World Championships 2007 Coimbra -84 kg

The men's 84 kg (184.8 lbs) semi-contact category at the W.A.K.O. World Championships 2007 in Coimbra was the fourth-heaviest of the male semi-contact tournaments falling between the light heavyweight and cruiserweight division when compared to the full-contact weight classes. There were eighteen fighters from four continents (Europe, North America, South America and Oceania) taking part in the competition. Each of the matches was three rounds of two minutes each and were fought under semi-contact rules.

Due to the less than required numbers for a thirty-two-man event, fourteen of the fighters had a bye through to the second round. The tournament winner was the Canadian Jason Grenier who won gold by defeating the Greek Andreas Aggelopoulos in the final match. Germany's Robert Knoedlseder and Croatian Zvonimir Gribl won bronze medals for reaching the semi-finals.
