The BDO World Darts Championship is a world championship competition in darts, organised by the British Darts Organisation (BDO). It began in 1978, and was the only world championship tournament up to and including 1993. Since 1994, following a dispute with the BDO and the subsequent fallout, a breakaway group (originally known as the World Darts Council, and now known as the Professional Darts Corporation) stages its own annual PDC World Championship, generally before the BDO version in late December and early January of each year.
