The 2018 NCAA Division III football season is the component of the 2018 college football season organized by the NCAA at the Division III level in the United States.
The season's playoffs ended with the NCAA Division III Football Championship, also known as the Stagg Bowl, at Woodforest Bank Stadium in Shenandoah, Texas.
Twenty-six conferences met the requirements for an automatic ("Pool A") bid to the playoffs.
Other than the NESCAC, which does not participate in the playoffs, the NEWMAC was the only conference with no Pool A bid, being in the second year of the two-year waiting period after beginning football sponsorship in 2017.
With the loss of Mount Ida, the ECFC fell one below the required seven members – not counting second-year provisional member Dean – and entered the first year of the two-year grace period, while the Liberty League was in the second year of the grace period.
