The 2023 FireKeepers Casino 400 was a NASCAR Cup Seriesrace held on August 6 and 7, 2023, at Michigan International Speedway in Brooklyn, Michigan. Contested over 200 laps on the two-mile (3.2 km) D-shaped oval, it was the 23rd race of the 2023 NASCAR Cup Series season. The race began on Sunday, August 6, before rain delayed it to Monday, August 7, after 74 laps were complete.
The race was held at Michigan International Speedway, a two-mile (3.2 km) moderate-banked D-shaped speedway located in Brooklyn, Michigan. The track is used primarily for NASCAR events. It is known as a "sister track" to Texas World Speedway as MIS's oval design was a direct basis of TWS, with moderate modifications to the banking in the corners, and was used as the basis of Auto Club Speedway. The track is owned by International Speedway Corporation. Michigan International Speedway is recognized as one of motorsports' premier facilities because of its wide racing surface and high banking (by open-wheel standards; the 18-degree banking is modest by stock car standards).
