NASCAR has signed O'Reilly Auto Parts to be the entitlement sponsor of the Xfinity Series beginning next year, the sanctioning body announced Monday. The series will be known as the NASCAR O'Reilly Auto Parts Series beginning in 2026.

NASCAR 's secondary racing division, the Xfinity Series, will undergo a name change in 2026 as a result of a new sponsorship deal with O'Reilly Auto Parts. Xfinity has held the naming rights since 2015, but that will change next year to the NASCAR O'Reilly Auto Parts Series.
