Mid-State 6 Conference

The Mid-State 6 Conference was a high school athletics conference in central Illinois, made up of the high schools in Peoria, Illinois plus various other schools over the course of its existence. It existed for several decades. Previous names included MidState 8 and MidState 9 in the 1960s, and Mid-State 10 in the 1980s and 1990s.

, the only schools remaining were in the city of Peoria: Peoria Notre Dame and the three general public high schools Manual, Peoria (Central), and Richwoods. Those schools were joined the Big 12 Conference in 2014.

History
After IVC High School and Quincy Notre Dame left the Mid-State 6, a merger with the Western Big 6 Conference was set to begin in 2013 with football. However, when Manual's prior obligation to play Eureka made it unable to schedule a game with Moline High School, the merger failed, with the Mid-State 6 schools instead playing officially as independents against Western Big 6 Conference schools in football during the 2013–2014 school year.
