The 1999 FedEx Championship Series season was the twenty-first in the Championship Auto Racing Teams (CART) era of American open-wheel car racing. It consisted of 20 races, beginning in Homestead, Florida on March 21 and concluding in Fontana, California on October 31. The season was marred by the fatal accidents of Gonzalo Rodríguez during practice for the Laguna Seca round and Greg Moore at the final round, in addition to various injuries that took several drivers out of championship contention.
Juan Pablo Montoya, in his first CART season after two successful seasons in International Formula 3000, won the championship and the Rookie of the Year honors, the second and final driver to win both awards in the same season, after Nigel Mansell in 1993. The season ended in a tie, with Montoya and Dario Franchitti both having 212 championship points, though Montoya broke the tie-breaker due to having seven wins, over Franchitti's three.
With Al Unser Jr. running his final season in the series, 1999 was the last year in which the Al Unser name was on the CART grid. Also, this was the first season without Bobby Rahal on the grid. Mercedes-Benz scored their final pole and victory with Greg Moore at the season opener before they ended their participation in American open-wheel racing at the end of 2000.
