The World Series of Darts was a professional darts tournament held from 19 to 21 May 2006 at the Mohegan Sun Casino, in Uncasville, Connecticut. It was the first and only edition of the competition, which was established by the Professional Darts Corporation (PDC) to capitalise on the potentially large North American market. It was the second of four PDC non-ranking events in the 2006 season and featured 32 players: 16 American entrants and 16 PDC players. There was a $1,000,000 bonus to the winner of the tournament if they were from the United States.
