Three human polls and one formulaic ranking make up the 2005 NCAA Division I-A football rankings, in addition to various publications' preseason polls. Unlike most sports, college football's governing body, the National Collegiate Athletic Association (NCAA), does not bestow a National Championship title for Division I-A football. That title is bestowed by different polling agencies. There are several polls that currently exist. The main weekly polls are the AP Poll and Coaches Poll. About halfway through the season, two additional polls are released; the Harris Interactive Poll and the Bowl Championship Series (BCS) standings.

During the 2005 season, 34 different teams appeared in the rankings by the major polls, but two teams, USC and Texas, held the top two spots throughout the course of the entire season.
