1977 Colorado Buffaloes football team

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 7–3–1 overall and 3–3–1 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 2–3–1 finish knocked them out of a bowl berth.
