The 1984 Colorado Buffaloes football team represented the University of Colorado in the Big Eight Conference during the 1984 NCAA Division I-A football season. Led by third-year head coach Bill McCartney, the Buffaloes finished at 1–10 (1–6 in Big 8, seventh), their sixth consecutive losing season. Home games were played on campus at sixty-year-old Folsom Field in Boulder, Colorado. Colorado's sole win came in mid-season, by two points over last-place Iowa State on homecoming. The Buffs' previous one-win season was four years earlier; the next was in 2012.
