The 2008 Idaho Vandals football team represented the University of Idaho during the 2008 NCAA Division I FBS football season. Idaho competed as a member of the Western Athletic Conference (WAC), and played their home games in the Kibbie Dome, an indoor facility on campus in Moscow, Idaho. The Vandals were led by second-year head coach Robb Akey.
The Vandals finished the season with a 2–10 overall record and 1–7 in conference play, which was the team's ninth-straight season with a losing record. Idaho's two wins were against in-state rival, an FCS program in the Big Sky, and conference foe New Mexico State. The victory over New Mexico State ended a 24-game losing streak against FBS opponents.
Eight of the Vandals' ten losses came by 23 points or more, and against Utah State, Idaho surrendered a third-quarter lead by yielding 28 unanswered points in the final period. Idaho was outgained by conference opponents by 151.6 yards per game on average.[1]
Idaho's reported home attendance in 2008 was 92,041 for six games, an average of 15,340 per game.
