The 1977 Colorado Buffaloes football team represented the University of Colorado Boulder in the Big Eight Conference during the 1977 NCAA Division I football season. Led by fourth-year head coach Bill Mallory, the Buffaloes were overall and in the Big 8.
Colorado was a defending conference co-champion and won its first five games to reach third in the polls in October, its highest rank in five years. A disappointing finish knocked them out of a bowl berth.
