NFC Championships (14) Super Bowl appearances (14) The 49ers–Cowboys rivalry is a National Football League (NFL) rivalry between the San Francisco 49ers and the Dallas Cowboys. The Cowboys lead the series 18-17-1. It is one of the great inter-division rivalry games in the NFL. The two teams do not play every year; instead, they play once every three years due to the NFL's rotating division schedules, or if the two teams finish in the same place in their respective divisions, they would play the ensuing season. Sports Illustrated ranked it as the eighth best rivalry while the NFL Top 10 ranked this rivalry to be the tenth best in the NFL. The rivalry was also the subject of two 2015 episodes of NFL Network's The Timeline series.
