The Ambetter Health 400 is a NASCAR Cup Series stock car race held at Atlanta Motor Speedway in Hampton, Georgia. Daniel Suárez is the defending race winner.

This race was originally Atlanta's second race of the season and was run as a late-season event for much of its history. From 1987 until 2001, the race was scheduled in November as the final race of the NASCAR season. From 2002 until 2008, the race was moved to October in favor of awarding the final race weekend to Homestead-Miami Speedway and became part of what is now the NASCAR Chase for the Championship in 2004. In 2009, Atlanta swapped fall race dates with Auto Club Speedway and the race was moved to Labor Day weekend. From 2011 to 2020, this was Atlanta's only Cup Series race date as its spring race was moved to Kentucky Speedway and run later in the year.

In 2015, the race lost its place as the Labor Day weekend race for the Cup Series and became the second race of the season (after the season-opening Daytona 500). In 2020, it was moved from being the second race of the season to being the first race after the west coast swing (the races at Las Vegas, Phoenix and Fontana), making it the fifth race of the Cup Series season. However, the race would end up being run in June that year due to the COVID-19 pandemic (and it was the first Cup Series race to be postponed due to the pandemic). In 2021, the race was held as scheduled in March as the fifth race of the season.
