The 2006 Grand Prix of Denver was the tenth round of the 2006 Bridgestone Presents the Champ Car World Series Powered by Ford season, held on August 13, 2006 on the streets of Denver, Colorado. Sébastien Bourdais took the pole while the race was won by A. J. Allmendinger. Bourdais' race ended when he and Paul Tracy crashed in the final turn of the final lap of the race as Tracy attempted to pass Bourdais to take second place. Tracy and Bourdais got into a confrontation outside their cars (pictured). Tracy was subsequently fined and penalized three championship points for avoidable contact for the incident.

The Grand Prix of Denver was a Champ Car race last held on a street circuit in Denver, Colorado, United States. A Champ Car race was first held in Denver in 1909 on a 14.5-mile (23.3-km) road circuit in nearby Brighton. Racing returned to the Centennial Park dirt oval in 1951 and 1952 under AAA sanctioning. 38 years later Champ Cars returned to Denver with a CART-sanctioned event downtown near the Civic Center. However, like the previous incarnation, that race also lasted only two years. CART returned to Denver in 2002 with a race on a 1.64-mile (2.64-km) temporary circuit around the then-named Pepsi Center. The final race was held in 2006. Champ Car initially put the race on its 2007 schedule but removed it after conflicts with other events could not be reconciled.
