The 1977 Dallas Cowboys season was their 18th in the National Football League (NFL). The club appeared twice on Monday Night Football. Rookie running back Tony Dorsett rushed for 1,007 yards and became the second member of the Cowboys (first since 1973) to have a 1,000-yard rushing season. Dallas scored 345 points, which ranked first in the NFC, while its defense only gave up 212 points. The Cowboys made it to their fourth Super Bowl and beat the Denver Broncos to capture their second Super Bowl title. They were the first team from the NFC East Division to win two Super Bowls. Their 15–2 (.882) record (including the postseason) remains the highest single-season winning percentage in franchise history.
