The list of SIAA football champions includes the teams that have won the college football championship of the Southern Intercollegiate Athletic Association since its creation. Twenty-seven of the current Division I FBS (formerly Division I-A) football programs were members of this conference at some point, as were at least 19 other schools. Every member of the current Southeastern Conference except Arkansas and Missouri, as well as six of the 15 current members of the Atlantic Coast Conference plus the University of Texas at Austin, now of the Big 12 Conference (and previously of the now defunct Southwest Conference), formerly held membership in the SIAA.
