The IIHF Women's World Hockey Championship is the premier international tournament in women's ice hockey. It is governed by the International Ice Hockey Federation (IIHF). Canada is the most successful nation with ten world titles followed by the United States with six.
The official world competition was first held in 1990, with four more championships held in the 90's. Beginning in 1989, and in years that there was no world tournament held, there were European Championships and in 1995 and 1996 a Pacific Rim Championship. As part of an effort to improve competition, the IIHF decided to hold Women's Championships in Olympic years, starting in 2014, but not at the top level.
