The 1977 BYU Cougars football team represented Brigham Young University (BYU) for the 1977 NCAA Division I football season. The Cougars were led by sixth-year head coach LaVell Edwards and played their home games at Cougar Stadium in Provo, Utah. The team competed as a member of the Western Athletic Conference, winning a share of the conference title for the second consecutive year, sharing the title with Arizona State with a conference record of 6–1.

The previous season, BYU was invited to the Tangerine Bowl, where they lost to Oklahoma State. Despite finishing the regular season with a record of 9–2 and ranked 17th in the AP Poll, the Cougars were not invited to a bowl game and dropped to twentieth in the final poll, and tied for sixteenth in the UPI Coaches Poll.^[1][2]
