The Southern Illinois River-to-River Conference (SIRR) is a high school athletic conference, currently represented by 11 schools in southern Illinois. The conference is divided into two divisions. While technically in the same conference each division crowns its own champion, and each winner is regarded as the conference champion as if they were in two separate conferences. Schools are only required to play other schools within their own division although cross-divisional play is very common.
