The 2012 IIHF U18 World Championship was the 14th IIHF World U18 Championship and was hosted in Brno, Znojmo and Břeclav, Czech Republic. It began on 12 April 2012 with the gold medal game played on 22 April 2012. Brno and Znojmo were originally to co-host, but a schedule change became necessary when Kometa Brno unexpectedly advanced to the Czech Extraliga finals, making their home ice unavailable to the tournament on three days. The United States defeated Sweden 7–0 in the final to win their seventh title. Canada captured the bronze medal by beating Finland 5–4 in overtime.
