The 1974 Ice Hockey World Championships were the 41st Ice Hockey World Championships and the 52nd European Championships in ice hockey. The tournament took place in Finland from 5 to 20 April and the games were played in the capital, Helsinki. Six teams took part in the main tournament, all playing each other twice. The Soviet Union won the world championships for the 13th time, and also won their 16th European title.
For the first time in ice hockey World Championship history, two players were suspended for doping. They were the Swede Ulf Nilsson and the Finn Stig Wetzell who failed a drug test for the forbidden substance ephedrine. Both players were suspended for the rest of the tournament. Nilsson failed the test after Sweden's game against Poland, which Sweden won 4–1. The game was awarded to Poland as a 5–0 forfeit. The Finn, Wetzell, failed the test after Finland's match against Czechoslovakia, which Finland won 5–2, which was also awarded to Czechoslovakia as a 5–0 forfeit. The Finns were able to defeat Czechoslovakia again on the last day, which would have earned the Finns their first medal in history, if not for the points lost in the forfeited win.
