The San Francisco 49ers have three rivals within their division: the Los Angeles Rams, the Arizona Cardinals, and the Seattle Seahawks. They also have rivalries with other teams that arose from post-season games in the past, most notably the Dallas Cowboys, New York Giants, and Green Bay Packers. They also share an intrastate rivalry with the Los Angeles Chargers (the two teams have played each other nearly every preseason, and every four years in the regular season, and also met in Super Bowl XXIX).[12]
