The Tri-Rivers Conference is a high school conference in eastern Iowa sponsoring athletic competition, as well as speech and music activities. Formed in 1967, the conference has enjoyed long-term stability while enduring periods of significant change over its 50-plus year history. With the return of Edgewood–Colesburg in 2017 (after a brief 4-year hiatus), all but one of the founding members were still conference members. (Center Point, following its merger with Urbana, simply out-grew its former competitors).
