The 2026 schedule for the newly named NASCAR O’Reilly Auto Parts Series has been revealed.
In addition to NASCAR’s second-tier series bringing in new series title sponsor O’Reilly Auto Parts, several changes occurred between the 2025 and 2026 schedules.
The previously announced race at Naval Base Coronado in San Diego is the most noticeable change fans will see next year, along with the return of Chicagoland Speedway, where the series hasn’t competed at since the 2019 season, replacing the previously announced departure from the Chicago street course.
