The 1999 World Grand Prix was the second staging of a darts tournament organised by the Professional Darts Corporation (PDC) and held at the Casino Rooms in Rochester, England between 20–24 October 1999.

Phil Taylor retained the title, beating Shayne Burgess 6-1 in the final.

Taylor's only close match came in the semi-finals, where he defeated Rod Harrington 5-4.

[1] The format employed for this tournament meant that players could still qualify for the quarter-finals even if they lost either of their first two matches.

The format was thus: Players in bold denote match winners.
