2006 NCAA Division I FBS football rankings
Three human polls and one formulaic ranking make up the 2006 NCAA Division I FBS football rankings, in addition to various publications' preseason polls. Unlike most sports, college football's governing body, the NCAA, does not bestow a National Championship title. That title is bestowed by one or more of four different polling agencies. There are two main weekly polls that begin in the preseason: the AP Poll and the Coaches Poll. About halfway through the season, two additional polls are released, the Harris Interactive Poll and the Bowl Championship Series Standings. The Harris Poll and Coaches Poll are factors in the BCS Standings. At the end of the season, the BCS Standings determine who plays in the BCS bowl games as well as the BCS National Championship Game.

AP Poll
Coaches' Poll
, head coach of the Ohio State Buckeyes, refused to vote in the Week 15 poll, citing a conflict of interest. In a change to the Coaches Poll for the 2006 season, the final ballots are made public. Tressel did not want his vote of picking Florida or Michigan to play against his team to be known publicly and therefore refused to vote and was an unprecedented move in that no Coaches Poll voter has ever refused to vote.| Preseason | Week 1 Sept 5 | Week 2 Sept 10 | Week 3 Sept 17 | Week 4 Sept 24 | Week 5 Oct 1 | Week 6 Oct 8 | Week 7 Oct 15 | Week 8 Oct 22 | Week 9 Oct 29 | Week 10 Nov 5 | Week 11 Nov 12 | Week 12 Nov 19 | Week 13 Nov 26 | Week 14 Dec 3 | Week 15 Jan 9 | ||
