The Buccaneers–Dolphins rivalry is between the Tampa Bay Buccaneers and Miami Dolphins of the National Football League. It is an in-state, interconference matchup between the two oldest NFL teams in the state of Florida. It has been active in most years since the Buccaneers joined the league as an expansion team in 1976. The rivalry is mostly a mainstay of the preseason, as the teams have been in different conferences since 1977 and as such only play each other during the regular season once every four years.
