2010 Star Mazda Championship
The 2010 IMSA Star Mazda Championship was the twelfth season of the Star Mazda Championship, an open wheel auto racing series that competes using spec chassis and engines. It was the third season under the sanctioning of the International Motor Sports Association and the first under the Indy Racing League's new Road to Indy ladder.
Conor Daly became series champion after finishing in the top four positions in each of the twelve races prior to clinching the title at Mosport International Raceway. At the same meeting, Carlos Conde sealed the Masters title for drivers over 45 years of age, while J. W. Roberts secured the Expert title for drivers between 30 and 44 at Trois-Rivières.
