The Missouri State High School Basketball Championships is an annual tournament that showcases the best high school basketball teams in Missouri. Organized by the Missouri State High School Activities Association (MSHSAA), the championships feature various classifications based on school size, allowing teams from different divisions to compete for the state title. The tournament typically takes place in March and includes both boys' and girls' competitions. Teams must qualify through district and sectional tournaments to reach the state finals, where they compete at a neutral site, often in a large arena, to determine the champions in each classification.
