Men's K-1 at WAKO World Championships 2007 Belgrade -91 kg

The men's heavyweight (91 kg/200.2 lbs) K-1 category at the W.A.K.O. World Championships 2007 in Belgrade was the second heaviest of the K-1 tournaments, involving twelve fighters from two continents (Europe and Africa). Each of the matches was three rounds of two minutes each and were fought under K-1 rules.

As there were not enough fighters for a sixteen-man tournament, four of the contestants had a bye through to the quarter-finals. Belarusian Andrei Malchanau ensured that his country kept up their excellent showing in the K-1 category by defeating Macedonia's Atanas Stojkovski to claim the gold. Serb Nenad Miletic and Croat Zoran Majkic won bronze medals for reaching the semi-finals.
