The 1977 Pittsburgh Steelers season was the franchise's 45th in the National Football League. After what was considered the franchise's greatest season ever in 1976, the 1977 Pittsburgh Steelers failed to improve on their 10-4 record from 1976 and finished with a 9-5 record, however they appeared in the playoffs for their 6th straight season and won the AFC Central again. They had a hard time for most of the season as their record hovered around .500. Even the Steel curtain seemed to have a little wear and tear allowing 243 points on the season, more than 100 more than the previous season. The sloppy plays would catch up with them in the Divisional Playoffs when they were knocked off by the Broncos 34–21 in Denver.
