The 1999 Marlboro Grand Prix of Miami was the first and opening round of the 1999 CART FedEx Champ Car World Series season, held March 21, 1999, on the Homestead-Miami Speedway in Homestead, Florida.

In an interview with ABC pit reporter Gary Gerould, Hearn noted he and the team had been having problems with the car all weekend, deciding to retire as to not impede other drivers.

Patrick Carpentier and Robby Gordon served drive-through penalties for not using the access road to properly enter the pits during the caution.

Greg Moore won the opening race of the season from pole, leading 96 out of the 150 laps,[2] winning comfortably ahead of Michael Andretti and Dario Franchitti before a crowd of roughly 40,000.

Andretti had won the race the previous two years, but accidentally shut off his engine during his pit stop under the 2nd caution.
