The 2006 Lakeside World Professional Darts Championship was held from 7 to 15 January 2006 at the Lakeside Country Club in Frimley Green, Surrey. Defending champion Raymond van Barneveld was aiming to win a fifth BDO world title, equalling the record set by Eric Bristow. However, he was beaten 7–5 in the final by Dutch qualifier Jelle Klaasen; the final was the first and only World Darts Championship final to not feature a British player. Klaasen became the youngest World Champion at age 21 and became the first qualifier to win the World Championship since Keith Deller in 1983, who became the youngest World Champion himself, aged 23. This would eventually be Van Barneveld's last appearance at the Lakeside as he would switch to the rival Professional Darts Corporation the next month.
It would be the only BDO Men's World Championship that had no representative from Wales.
