The 2004 Idaho Vandals football team represented the University of Idaho during the 2004 NCAA Division I-A football season.

Idaho competed as a member of the Sun Belt Conference, and played their home games in the Kibbie Dome, an indoor facility on campus in Moscow, Idaho.

Led by first-year head coach Nick Holt, the Vandals finished at 3–9 (2–5 in Sun Belt, last).

[1][2] The season was marred by the September death of starting cornerback Eric McMillan, a redshirt freshman from Murrieta, California, and originally from Tuskegee, Alabama.

In a case of mistaken identity, he was shot in his apartment in south Moscow on Sunday afternoon, a day after the third game of season, and died at Gritman Medical Center.
