A16. The Pittsburgh Steelers and the Dallas Cowboys
It shouldn't be much of a surprise that one of the team that played in the most Super Bowl games also has had the most repeat opponents. The Steelers and Cowboys competed against each other in 1976, 1979, and 1996. The Steelers currently have the lead.
There have been 9 official Super Bowl rematch games (Super Bowl LVIII included).
