The Associated Press released its first Top 25 college football poll in 1936. Since then, there have been 64 NCAA-recognized undefeated college football champions, including co-title holders. Notre Dame has the most undefeated, championship-winning campaigns with six, followed by Nebraska and Alabama with five apiece.

At the end of Week 11 of the 2025 college football season , three teams remain undefeated: Ohio State , Indiana , and Texas A &M . Only time will tell if one of these squads can extend their successful run to take home a national championship.
