The 2021 Sparks 300 was a NASCAR Xfinity Series race held on October 2, 2021, at Talladega Superspeedway in Lincoln, Alabama.

After "The Big One" occurred late, Brandon Brown was determined as the leader at the time of caution.

The race was then called due to darkness, leading to his first career Xfinity series victory.

The track is a tri-oval and was constructed in the 1960s by the International Speedway Corporation, a business controlled by the France family.

Justin Allgaier was awarded the pole for the race as determined by competition-based formula.
