The Central States Football League (CSFL) was a college athletic conference affiliated with the NAIA. Member institutions were located in Oklahoma, Texas, Arkansas and Arizona and competed only in football. The conference was established in 2000 and its charter members included Haskell Indian Nations University, Langston University, Northwestern Oklahoma State University, Southwestern Assemblies of God University, and Peru State College. In 2017, the Sooner Athletic Conference, which served as the primary conference for the majority of the CSFL's membership decided to sponsor football beginning in 2018. As a result the conference's membership shifted to that conference.
