The Cowboys–Rams rivalry is a National Football League (NFL) rivalry between the Dallas Cowboys and the Los Angeles Rams. 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. The rivalry between the two teams peaked during the 1970s and early-to-mid 1980s, during which they met eight times in the playoffs, with each team winning four.
