Two human polls comprised the 1989 National Collegiate Athletic Association (NCAA) Division I-A football rankings. Unlike most sports, college football's governing body, the NCAA, does not bestow a national championship, instead that title is bestowed by one or more different polling agencies. There are two main weekly polls that begin in the preseasonāthe AP Poll and the Coaches Poll.
