K-1 World Grand Prix 2001 Final was a kickboxing event promoted by the K-1. The event was held at the Tokyo Dome in Tokyo, Japan on Saturday, December 8, 2001, in front of 65,000 spectators. It was the ninth K-1 Grand Prix final, involving eight of the world's top fighters, with all bouts fought under K-1 Rules (100 kg/156-220 lbs). The eight finalists had almost all qualified by winning preliminary tournaments (with the exception of Peter Aerts who was a runner up), while two additional fighters were invited as reserve fighters in case of any injuries.
