The 2023 Quaker State 400 was a NASCAR Cup Series race held on July 9, 2023, at Atlanta Motor Speedway in Hampton, Georgia. Originally scheduled for 260 laps on the 1.54-mile-long (2.48 km) asphalt quad-oval intermediate speedway (with superspeedway rules), the race was shortened to 185 laps due to rain. It was the 19th race of the 2023 NASCAR Cup Series season.

Atlanta Motor Speedway is a track in Hampton, Georgia, 20 miles (32 km) south of Atlanta. It is a 1.54-mile (2.48 km) quad-oval track with a seating capacity of 111,000. It opened in 1960 as a 1.5-mile (2.4 km) standard oval. In 1994, 46 condominiums were built over the northeastern side of the track. In 1997, to standardize the track with Speedway Motorsports' other two 1.5-mile (2.4 km) ovals, the entire track was almost completely rebuilt. The frontstretch and backstretch were swapped, and the configuration of the track was changed from oval to quad-oval. The project made the track one of the fastest on the NASCAR circuit.
