The Tennessee Secondary School Athletic Association (TSSAA), along with the affiliated Tennessee Middle School Athletic Association (TMSAA), is an organization which administers junior and senior high school sporting events in Tennessee. The TSSAA (commonly pronounced "Tee double-S double-A") is the only high school athletic organization in the United States to have a five-sport, Olympic-style spring sport championship tournament, known as Spring Fling, for baseball, softball, track and field, team and individual tennis, and soccer. Spring Fling began in Chattanooga in 1993, later moving to Memphis, and then establishing itself in Murfreesboro. The TSSAA was one of the first high school athletic organizations to host a central site for football championships, beginning in 1982.
