Mississippi State University has not won any NCAA football national championships. The closest they came was in the 2014 season when they finished the regular season ranked No. 1 in the College Football Playoff rankings, but they did not secure a national title. The program has a storied history and has achieved significant success, but a national championship has eluded them.
