2001 Idaho Vandals football team

The 2001 Idaho Vandals football team represented the University of Idaho during the 2001 NCAA Division I-A football season. Idaho was a football-only member of the Sun Belt Conference. The Vandals' head coach was alumnus Tom Cable, in his second season, and Idaho was 1–10 overall, 1–5 in conference, their lowest win total since 1960, and most losses in a season.

Idaho played its November home games at the Kibbie Dome, an indoor 16,000-seat facility on campus in Moscow, Idaho; earlier home games in 2001 were held at Martin Stadium at Washington State University in nearby Pullman, Washington.

This was the first year of football competition in the Sun Belt Conference, which included four of the six members of the Big West from the previous football season; the three that moved to full membership were Arkansas State, New Mexico State, and North Texas. Idaho and Utah State stayed in the Big West for other sports, but the Aggies went independent for football (for two seasons). Boise State joined the Western Athletic Conference (WAC), marking the first time Idaho and BSU were not in the same conference since 1969, when the Broncos were an NAIA independent.
