Berlin Raceway is a 7/16 mile long paved oval race track in Marne, Michigan, near Grand Rapids. The track races weekly as part of NASCAR's Whelen All-American Series. It currently hosts a race in the ARCA Menards Series East tour. The track has held touring series events on the ARCA Menards Series, American Speed Association National Tour, USAC Stock Cars, USAC Silver Crown, World of Outlaws Sprint cars, and World of Outlaws Late Model Series tours.

The track opened in 1950. It was originally a horse track before World War II. Berlin's current track record is 12.513 seconds, set by Brian Gerster in 2018 in a winged sprint car. Berlin Raceway takes its name from the city of Marne's original name "Berlin," which was changed due to Anti-German sentiment following World War I.

The track was developed by the Chester Mysliwiec family in 1950. It was purchased by the West Michigan Whitecaps in 2001. The group made numerous improvements to the facilities such as new bathrooms, updated catch fences, and a new sound system. Dirt was temporarily placed over the pavement after the 2017 regular season and three touring series visited the track in September / October - American Ethanol Late Model Tour, American Ethanol Modified Tour and Engine Pro Sprints On Dirt. Some racing scenes for the movie God Bless the Broken Road were recorded at the track in early 2016 for the 2018 film. The track dropped its Super Stock and Modified classes in 2020 and added a class of Limited Late Models. Other classes include Super Late Models, Sportsman, 4 Cylinder, and Mini-Wedges.

Qualifying would take place on Saturday, July 17, at 6:00 PM EST.^[2] Each driver would have two laps to have a chance to set a lap, and the fastest of the two would be taken. Daniel Dye of GMS Racing would win the pole, setting a time of 16.468 and an average speed of 95.640 miles per hour (153.918 km/h).
