2009 NCAA Division I FBS football season

The 2009 NCAA Division I FBS football season was the highest level of college football competition in the United States organized by the National Collegiate Athletic Association (NCAA).

The regular season began on September 3, 2009, and ended on December 12, 2009. The postseason concluded on January 7, 2010, with the BCS National Championship Game in Pasadena, California, where the Alabama Crimson Tide defeated the Texas Longhorns by the score of 37–21.

For the first time in the history of the Heisman Trophy, the annual award for the most outstanding player in college football, two previous Heisman winners played in the same season—2008 winner Sam Bradford of Oklahoma and 2007 winner Tim Tebow of Florida. For the first time since 1946, the top three vote-getters from the previous season all returned: Bradford, Colt McCoy of Texas, and Tebow, in that order. Six teams finished the regular season undefeated; a record for the BCS era.
