K-1 World MAX 2003 World Tournament final

K-1 World MAX 2003 World Tournament Final was a kickboxing event promoted by the K-1 organization. It was the second ever K-1 MAX final for middleweight kickboxers (70 kg/154 lb weight class) involving eight finalists and two reserve fighters, with all bouts fought under K-1 rules. The tournament fighters had qualified via preliminary tournaments, had been involved in the previous years final, or had been invited due to their achievements in kickboxing and Muay Thai (more information on the fighters is detailed by the bulleted list below). As well as tournament bouts there was also a super fight, also fought under K-1 rules. In total there were twelve fighters at the event, representing seven countries.

The tournament winner was the home favourite Masato who defeated reigning champion Albert Kraus by knockout, in what was a very entertaining event with five stoppages in the eight bouts. Both Masato and Kraus had challenging routes to the final with Masato having a close decision victory over Mike Zambidis and Kraus overcoming up and comer and future K-1 MAX champion Andy Souwer in the quarter-finals. The event was held in Saitama at the Saitama Super Arena, on Saturday, 5 July 2003.
