The GT World Challenge America is a North American auto racing series launched in 1990 by the Sports Car Club of America. It has been managed by the SRO Motorsports Group since 2018, and has been sanctioned by the United States Auto Club since 2017.

The series consists of four driver classifications and five classes of vehicles: GT3, GT4, (Sprint, SprintX, East and West), and Touring Car, consisting of TCR homologated cars, as well as separate TC and TCA classes featuring modified production vehicles, such as the BMW M235iR and the Mazda MX-5 Cup car.
