The 1966 World Ice Hockey Championships was the 33rd edition of the Ice Hockey World Championships. The tournament was held in Hala Tivoli, Ljubljana, SR Slovenia, Yugoslavia from March 3 to March 14, 1966. For the fourth straight year, the Soviet Union won the tournament. For the Soviets, it was their sixth World and tenth European title. The Czechs beat both Canada and Sweden two to one, to take the Silver, while the Swedes additional losses to Canada and (shockingly) East Germany, put them fourth behind Canada for the Bronze.
The lower two tiers (Groups B and C) were formalized, so there would be no more qualifying tournaments with promotion and relegation taking places between these two tournaments as well. West Germany won all their games to return to the top level of competition while Great Britain went winless and was replaced by Group C winner Italy.

European Championship medal table 
Please note: At the time of the championship Sweden was awarded the bronze, however, East Germany should have won because of their better record amongst only European clubs. In 1999 this mistake was corrected and living players were presented with the medals they were supposed to have won.
