The 2004 World's Strongest Man was the 27th edition of World's Strongest Man and was won by Vasyl Virastyuk from Ukraine. It was his first title after finishing third the previous year. Zydrunas Savickas from Lithuania finished second for the third year in a row. Originally Mariusz Pudzianowski from Poland finished third, but was later disqualified after testing positive for a banned substance, thus third place was given to Magnus Samuelsson from Sweden. The contest was held in Nassau, Bahamas. The qualifying heats saw a major format change, going from the traditional 5-6 man heats with the top 2 going to the finals. This year's format was a 12-man round-robin competition taking place over 5 days, with the top six going onto the finals.
