NASCAR Cup Series at Chicagoland

Stock car races in the NASCAR Cup Series are held at the Chicagoland Speedway in Joliet, Illinois, currently known as the eero 400 for sponsorship reasons. Previously, the race was held in July from 2001 through 2010, with night races held from 2008 to 2010. From 2011 to 2017, the races were held as the first race of the Cup Series playoffs in the round of 16. In 2018, as part of the schedule realignment, the race was held on the last weekend of June. The race was placed on hiatus from 2020 to 2025 and returned in 2026.
