The Southern Illinois 100 (formerly the Rust-Oleum Automotive Finishes 100) is an ARCA Menards Series stock car race held annually on the DuQuoin State Fairgrounds Racetrack during the DuQuoin State Fair on Labor Day weekend.

It is one of two dirt races on the ARCA schedule, the other being the Springfield ARCA 100 at the Illinois State Fairgrounds Racetrack, both of which are longtime events on the series schedule. These two races are part of the Performance Seed Dirt Double, which is a $20,000 bonus that is given to a driver who wins both races (the last time it happened was Parker Kligerman in 2009) and if not, bonuses are given to the drivers with the three best average finishes in the two races ($7,500 for first best, $5,000 for second best and $2,500 for third best).^[1]
