The Iowa Corn 350 (officially known as the Iowa Corn 350 powered by Ethanol) is a NASCAR Cup Series stock car race held at Iowa Speedway in Newton, Iowa.[2] It was NASCAR Cup Series' first race at Iowa Speedway and first race in the state of Iowa.[3][4]

William Byron is the defending race winner, having won it in 2025.

History

Prior to 2024, NASCAR's lower two series, the NASCAR O'Reilly Auto Parts Series and the NASCAR Craftsman Truck Series, had races held at the track from 2009 (Trucks)/2011 (O'Reilly) until 2019;[5][6] the races were removed from both series' 2020 calendars as a result of the COVID-19 pandemic-induced realignment, and did not return for either series' 2021 calendar.[7] Initially, there were no plans of hosting the Cup Series at the track, due to lack of room in the schedule;[8] following a management change in 2018, expansion plans were drawn up in order to make the track as part of the Cup Series calendar.[9]

When Iowa Speedway became part of the Cup calendar in 2024, it replaced the Pala Casino 400 due to planned construction at the Auto Club Speedway.[10] It was a late decision to race at Iowa Speedway as NASCAR were in discussions to race at Montreal, but no deal was made in time.[11] The O'Reilly Series also returned to the track with the Hy-Vee PERKS 250, although the Truck Series did not.

The inaugural running of the race, held under the lights on Father's Day, featured Ryan Blaney winning a race plagued by tire issues, as the turns were repaved.[12][13]

In 2025, the race moved to the first race of NBC's portion in early August due to a new TV deal.[14]
