The 2021 Corn Belt 150 presented by Premier Chevy Dealers was the 14th stock car race of the 2021 NASCAR Camping World Truck Series season and the inaugural running of the event, after Eldora Speedway's dirt race was moved to Knoxville Raceway. The race was held on Friday, July 9, 2021 in Knoxville, Iowa at Knoxville Raceway. The race was extended to 179 laps from the scheduled 150 laps due to numerous green-white-checker attempts. Austin Hill driving for Hattori Racing Enterprises would survive and win the event after dodging numerous wrecks and a wild ending to the event. Chandler Smith of Kyle Busch Motorsports and Grant Enfinger of ThorSport Racing would be able to come in 2nd and 3rd, respectively. Norm Benning would get his first Top 20 of the year, in a damaged truck finishing 19th.
