The 2012 Lakeside World Professional Darts Championship was the 35th BDO World Darts Championship organised by the British Darts Organisation, and the 27th staging at the Lakeside Country Club at Frimley Green. It ran from 7–15 January. Martin Adams was the defending men's champion, having won the title for the third time in the previous year's final against Dean Winstanley. The defending women's champion was Trina Gulliver, who won her ninth title in the 2011 final against Rhian Edwards. Neither champion was able to defend their title as Adams lost his quarter-final against Tony O'Shea and Gulliver her semi-final against Anastasia Dobromyslova. Dobromyslova then beat Deta Hedman in the final to win her second world championship title. O'Shea was defeated by unseeded qualifier Christian Kist, who was making his début in the tournament, 7–5 in the final. It was the first time that neither champion was from Great Britain (Christian Kist from the Netherlands and Anastasia Dobromyslova from Russia), despite both losing finalists coming from England (Tony O'Shea and Deta Hedman).
