The Music City 150, (currently called the Cook Out Music City 150 for sponsorship reasons) is a 89.400-mile (143.875 km) annual ARCA Menards Series East race held at the Nashville Fairgrounds Speedway in Nashville, Tennessee. The event has been part of the ARCA Menards Series and ARCA Menards Series East (previously the NASCAR Busch and Camping World East Series) schedules and has come and gone from both throughout its history. It was originally held in 1992 in what was then known as the ARCA SuperCar Series, brought back in 2007 and 2008 as an East Series race, brought back in 2015 as an ARCA Racing (later Menards) Series race, and then moved back to the East Series after NASCAR's acquisition of ARCA.

ARCA first raced at the Nashville Fairgrounds Speedway in 1992 and that year the race was won by David Green. The race did not return to the schedule in 1993 and would not return again until 2015.

During its first stint on the East Series schedule in 2007 and 2008, the race was 150 laps instead of the 200 laps that it has had in all the other years it has been run. Rogelio López and Matt Kobyluck won the two East Series races held at the track in 2007 and 2008, respectively.

The race was a late addition to the 2020 ARCA Menards Series East schedule. The rest of the races on the schedule had been announced a month earlier. However, due to the COVID-19 pandemic, the 2020 race ended up being cancelled. It was not rescheduled for another date later in the season. Unlike some of the other cancelled races on the East Series schedule, it was not replaced by another race at a different track.

Crosley Brands became the title sponsor of the race in 2021. They did not return in 2022 and another title sponsor was not found, and as a result, the race went back to the name it has had in the years it has not had a title sponsor, the Music City 200.

In the 2024 race, the race returned to being 150 laps in length.

For the 2026 race, the race continued to be 150 laps in length.
