Pontiac is a brand of automobiles first produced in 1926, and sold in the United States, Canada and Mexico by General Motors (GM), marketed as an "athletic" brand specializing in mainstream performance vehicles.

On April 27, 2009, amid ongoing financial problems and restructuring efforts, GM announced that it would phase out the Pontiac brand by the end of 2010 and focus on four core brands in the U.S. : Chevrolet, Cadillac, Buick, and GMC.
