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 junior and senior championships for each gender. 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 and Norway have all won at least one championship.

The World Curling Championships began in 1959 as the Scotch Cup. The first three Cups were contested between men's teams from Scotland and Canada. The United States joined the Scotch Cup in 1961, and Sweden also joined the next year. Canada won the first six world titles, of which the legendary rink skipped by Ernie Richardson earned four. The United States was the first country to break Canada's streak, winning their first world title in 1965. By 1967, Norway, Switzerland, France, and Germany were added to the Scotch Cup, and Scotland won their first title, while Canada finished without a medal for the first time. The tournament was renamed the Air Canada Silver Broom the year after that, and Canada strung together five consecutive world titles starting in that year.
