1984 Miami Dolphins season

The 1984 Miami Dolphins season was the team's 19th season, and 15th in the National Football League (NFL). It was also the 15th season with the team for head coach Don Shula. The Dolphins sought to build on a spectacular 1983 season where they went 12–4 with rookie quarterback Dan Marino.

The Dolphins won the 1984 AFC Championship, and appeared in Super Bowl XIX, where they lost to the San Francisco 49ers, 38–16. To date this is the last season the Dolphins appeared in the Super Bowl.

Second year quarterback Dan Marino's passing ability became the focal point of Miami's offense and in 1984 he exploded to set league records with 5,084 passing yards and 48 touchdowns. Marino's touchdown record was broken by Peyton Manning twenty years later and the yardage record was broken by Drew Brees twenty-seven years later. The Dolphins attempted early on to make a run at a perfect season twelve years after pulling off the feat, as they won their first eleven games but were upended in overtime by the San Diego Chargers. The Dolphins scored more than 500 points for the first and to date only time in their history, as they scored 513 points and finished 14–2, their best record since the undefeated season.

The year began on a somber note, as running back David Overstreet was killed in a traffic collision in June. The Dolphins wore helmet decals with the number 20 (his jersey number) in his memory during this season.

NFL Films produced a documentary about the team's season entitled Movers, Shakers and Record Breakers; it was narrated by Brad Crandall.

After the season, the last remaining Dolphin from their Super Bowl VIII team, longtime offensive lineman Ed Newman, retired, ending a 12-year era for the team. He holds the unique distinction as being the only man to make it to Super Bowl VIII and Super Bowl XIX as a member of the Dolphins, as well as Super Bowl XVII in between.
