The following lists Missouri high schools and the athletic conferences in which they compete. Under the current system used by the Missouri State High School Activities Association, some conference member teams may also compete in the same playoff district, while others are in districts with non-conference members. As a general rule, most conferences contain schools within their region and of similar class size, the class based on school enrollment. There are also some smaller, sport-specific conferences in Missouri, such as the Quad County and West Central for football, but the ones listed are the primary conferences for all sports.
