The 2011 Rolex Sports Car Series season was the twelfth season of Grand-Am's premier series.The season began with the Rolex 24 at Daytona on January 29 and finished with the EMCO Gears Classic at the Mid-Ohio Sports Car Course on September 17.

Continental Tire became the official tire partner and supplier for Grand-Am, replacing Pirelli after three seasons due to Pirelli's departure to FIA Formula 1 World Championship, GP2 Asia Series and GP2 Series (now FIA Formula 2 Championship) as well as increasing GP3 Series (now FIA Formula 3 Championship) involvement as an official tire partner and supplier after FIA World Motor Sport Council meeting verdict event in Geneva, Switzerland on June 24, 2010. The company purchased the naming rights of the RSCS's support series, the Grand-Am Cup Series, from KONI in 2010.

A notable change is the television coverage. In contrast to 2010, about half of the races were not televised live.

Schedule

The official schedule was released October 18, 2010, and consisted of twelve rounds. Road America appears on the schedule after a nine-year absence, while Laguna Seca returns after its absence from the schedule in 2010. The second race at Daytona and Miller Motorsports Park do not return.
