The Missouri State High School Activities Association (MSHSAA) is the governing body for high school activities throughout the state of Missouri. Approximately 580 high schools are members of MSHSAA.

The MSHSAA conducts championship-level activities in 23 activities. At least 50 member high schools must sponsor a sport for an official championship series to be conducted. Sports such as boys volleyball, field hockey, girls lacrosse, boys softball, and water polo are considered "emerging sports" by MSHSAA, but an official postseason series does not exist with less than 50 schools involved in those activities. MSHSAA also administers sideline cheerleading and dance team activities.
