The Grand Prix of Charlotte was a sports car race held at the infield road course of the Charlotte Motor Speedway in Concord, North Carolina. The race was held sporadically in the 1970s by the IMSA GT Championship and also the revamped Can-Am series. IMSA held five straight races beginning in 1982. The race was revived in 2000 by the American Le Mans Series, and has not been held since.
