The 1933 Ice Hockey World Championships were held between February 18 and February 26, 1933, in Prague, Czechoslovakia.
By winning its first world championship, the United States deprived Canada of the world title for the first time in tournament history. The American team, the Massachusetts Rangers, was mostly made up of university students and led by standout performances of Gerry Cosby in goal and team captain Ben Langmaid on defence. Canada was represented by the Toronto National Sea Fleas, winners of the 1932 Allan Cup, and coached by the controversial hockey personality Harold Ballard. The teams met on February 26 at Zimní stadión on Štvanice island. Tied 1-1 after 45 minutes of regulation time on goals by Sherman Forbes for the United States and an equalizer by Canadian Tim Kerr, defenceman John Garrison beat Canadian goalie Ron Geddes at the 6-minute mark of a dramatic "non-sudden death" overtime period.
