The 2005 NCAA Division I-A 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 1, 2005 and ended on December 3, 2005. The postseason concluded on January 4, 2006 with the Rose Bowl, which served as the season's BCS National Championship Game.
The USC Trojans and the Texas Longhorns finished the regular season as the only undefeated teams in Division I-A and consequently met in the Rose Bowl to play for the national title. Texas defeated USC largely due to the performance of quarterback Vince Young, who gained 467 yards of total offense and ran for three touchdowns. The Longhorns won their first national championship since 1970, and their first consensus national title since 1969.
