Two human polls comprised the 1968 NCAA University Division 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.
For the 1968 season, the AP Poll returned to ranking 20 teams per week, after ranking only 10 per week from 1961 to 1967.
This was also the second time (first since 1965) that the final AP Poll was conducted in January after the completion of bowl season, rather than at the end of the regular season.
The final UPI Coaches Poll was released prior to the bowl games, in early December.
