The Eldora Dirt Derby was a 75-mile-long (121 km) annual race in the NASCAR Gander RV & Outdoors Truck Series race held at Eldora Speedway in Rossburg, Ohio. During its existence from 2013 to 2019, the race was the only dirt track racing event on any NASCAR national touring series (Cup, Xfinity, or Truck) schedule and the first since 1970. Due to coronavirus concerns in 2020, the race was not run and is not scheduled to be run again in the Truck Series. The standalone dirt event was later moved to Knoxville Raceway for 2021.
