The 1980 Idaho State Bengals football team represented the Idaho State University as a member of the Big Sky Conference during the 1980 NCAA Division I-AA football season. Led by first-year head coach Dave Kragthorpe, the Bengals compiled an overall record of 6–5 (4–4 in Big Sky, fourth). Home games were played at the ASISU Minidome (now Holt Arena), an indoor venue on campus in Pocatello, Idaho.
Before their first win in late September, ISU had lost eighteen consecutive games, the longest losing streak in Division I-AA.[1] The homecoming victory over Montana in mid-October was the Bengals' first conference win in nearly three years.[2]
Previously the offensive line and assistant head coach at Brigham Young University, Kragthorpe was hired in late November 1979,[3] following the resignation of Bud Hake after a winless season.[4]
