The World Curling Championships are the annual world championships for curling, organized by the World Curling Federation and contested by national championship teams. There are men's, women's and mixed doubles championships, as well as men's and women's versions of junior and senior championships. There is also a world championship for wheelchair curling. The men's championship started in 1959, while the women's started in 1979. The mixed doubles championship was started in 2008. Since 2005, the men's and women's championships have been held in different venues, with Canada hosting one of the two championships every year: the men's championship in odd years, and the women's championship in even years. Canada has dominated both the men's and women's championships since their inception, although Switzerland, Sweden, Denmark, Germany (West Germany), Scotland, the United States, Norway and China have all won at least one championship.
