The 1999 Miami Dolphins season was the 34th year of existence for the Miami Dolphins franchise. The year saw the team struggling with the end of Dan Marino's career. Although they made the second wild card spot with a 9–7 record, and managed to upset the Seattle Seahawks in the Wild Card round, they were humiliated by the Jacksonville Jaguars in the Divisional round in the most lopsided playoff game of the Super Bowl era.
The Seattle Seahawks played host to their first playoff game since the 1988 Season. The Seahawks were dominated by the Dolphins defense, who held them to only 171 yards, with just 32 in the second half, and sacked quarterback Jon Kitna six times, three by Trace Armstrong. Although Seattle jumped out to a 17–10 lead in the 3rd quarter, the Dolphins would rally back behind quarterback Dan Marino, who threw for 196 yards and a touchdown, leading his team to their first road playoff win since 1972 in what ultimately proved to be the final game played at The Kingdome (the Seahawks moved into Qwest Field for the 2000 season) and the final win of Marino's career.
The Jacksonville Jaguars shredded their in-state rivals the Dolphins with 520 total offensive yards in what became Miami quarterback Dan Marino's last game in the NFL and the most lopsided postseason contest since the Chicago Bears defeated the Redskins 73–0 in the 1940 NFL championship game. Their defense forced seven turnovers and held the Dolphins to 131 total yards. Marino was held to just 11 of 25 completions for 95 yards and 1 touchdown, with 2 interceptions and a fumble that was returned for a touchdown in his final game. Marino retired shortly after the season ended.
This was also Jimmy Johnson's final game as an NFL head coach. Johnson resigned the day after the game.
