The 2004 Las Vegas Desert Classic, promoted at the time as the Las Vegas Desert Classic III, was the third year that the Professional Darts Corporation held a major darts tournament in the United States.

The layout of the playing hall had been modified from the previous year, and attracted larger crowds.

The tournament was won by Phil Taylor, who beat Wayne Mardle 6–4 in sets in the final.

Phil Taylor had the highest average in the best of 3 sets matches of 100.6 and coverage began live on Sky Sports with Round Two, the last 16 on Thursday 1 July.

The last American in the tournament, Darin Young (who was World Soft Tip Darts Champion) had beaten Lionel Sams in the first round and faced "Hawaii 501" – Wayne Mardle.

John Part also had a comfortable win against Adrian Gray and in the early stages of the match he was averaging 111.33.

John Part overcame Richie Burnett 3-1 in a match that wasn't necessarily reflected by the scoreline.

The first set went to the deciding leg, and Coote held a 2–1 lead in the second – but Taylor always had the better of his opponent when it mattered and won the match 3–0.

Dennis Smith had been suffering from toothache throughout the tournament and combined with an in-form Kevin Painter was too much for "Smiffy" winning 3–1 Part was dogged by a failure to hit his doubles against Mardle in the semi.
