The 2008 Boise State Broncos football team represented Boise State University in the 2008 NCAA Division I FBS football season. The Broncos played their home games at Bronco Stadium, most famous for its blue artificial turf surface, often referred to as the "smurf-turf". The blue turf was new for the 2008 season, as the old Astroplay surface was replaced by Field Turf. The Broncos won the Western Athletic Conference championship and were one of only two teams (the other being the Utah Utes) to finish the 2008 regular season with an undefeated record. However, the Broncos were unable to finish the season undefeated after losing 17–16 to #11 TCU in the Poinsettia Bowl.
