The World Billiards Championship is an international cue sports tournament in the discipline of English billiards, organised by World Billiards, a subsidiary of the World Professional Billiards and Snooker Association (WPBSA). In its various forms, and usually as a single competition, the title is one of the oldest sporting world championships, having been contested (though irregularly) since 1870.
From 2012 to 2014 there were separate timed and points divisions, with the tournament held in association with the International Billiards and Snooker Federation. In those years, there was no separate IBSF World Billiards Championship.
The rules adopted by the Billiards Association in 1899 are essentially the rules still used today. The tournament has been played on a regular annual schedule since 1980, when it became administered by the WPBSA. The event was known as the World Professional Billiards Championship until 2010, and has had other names in the past, e.g. Billiards Championship of the World. In addition, the World Ladies Billiards Championship has been played since 1931 (with interruptions) and organized by World Ladies Billiards and Snooker since 1998.[1]
