The 2021 Michelin GT Challenge at VIR was a sports car race sanctioned by the International Motor Sports Association (IMSA). The race was held at Virginia International Raceway in Alton, Virginia on October 9, 2021. The race was the eleventh round of the 2021 IMSA SportsCar Championship, and the eighth round of the WeatherTech Sprint Cup.

Background

International Motor Sports Association's (IMSA) president John Doonan confirmed the race was part of the schedule for the 2021 IMSA SportsCar Championship (IMSA SCC) in September 2020. It was the eighth consecutive year it was part of the IMSA SCC. The 2021 Michelin GT Challenge at VIR was the eleventh of twelve sports car races of 2021 by IMSA, and it was the eighth round held as part of the WeatherTech Sprint Cup. The race was held at the seventeen-turn Virginia International Raceway in Alton, Virginia. As in previous years, the event was also the second GT-only round of the IMSA SportsCar Championship season, in which only the GTLM and GTD classes were scheduled to compete.

Originally scheduled to run on August 22, 2021, the race was set to clash with the 24 Hours of Le Mans after the event was postponed from its original date in June to August. As a result, IMSA rescheduled the event to October 9, 2021, and moved Petit Le Mans to November 13, 2021.

On September 30, 2021, IMSA released the latest technical bulletin outlining Balance of Performance for the event. In GTD, the Lexus RC F GT3 received a 10 kilogram weight break. No changes were made in GTLM.

Before the race, Antonio García and Jordan Taylor led the GTLM Drivers' Championship with 2917 points, 160 points ahead of Tommy Milner and Nick Tandy followed by Cooper MacNeil in third. With 2570 points, the GTD Drivers' Championship was led by Zacharie Robichon and Laurens Vanthoor, ahead of Madison Snow and Bryan Sellers. Chevrolet and Porsche were leading their respective Manufacturers' Championships, while Corvette Racing and Pfaff Motorsports each led their own Teams' Championships.

A total of 18 cars took part in the event, split across 2 classes. 3 cars were entered in GTLM, and 15 in GTD. In GTLM, Kévin Estre would be joining Cooper MacNeil in the #79 WeatherTech Racing entry. GTD saw various changes after the previous round, as Alegra Motorsports would return after skipping the previous 3 rounds. Gilbert Korthoff Motorsports also returned for the first time since the Road America race with Mike Skeen partnering Guy Cosmo.
