List of Miami Dolphins seasons

This is a list of seasons completed by the National Football League (NFL)'s Miami Dolphins, an American football franchise based in the Miami metropolitan area. The list documents the season-by-season records of the Dolphins franchise from 1966 to present, including postseason records, and league awards for individual players or head coaches.

Although the Miami Dolphins were not successful before joining the NFL, from 1970 when they played their first season after the AFL–NFL merger until 2001 they were one of the most successful teams in the league, playing in the postseason on 22 occasions over those 32 years and winning 273 and tying two of 528 games for an overall win percentage of 63.6. Early in this period the Dolphins won their only two Super Bowls in consecutive seasons, in the process achieving the only modern-day perfect season in any major professional sports league during only their third year in the NFL. Much of this success was orchestrated by coach Don Shula who joined the team in 1970 and stayed with them until his retirement in 1995.

After Shula retired in 1995, the Dolphins remained a force for six years under successors Jimmy Johnson and Dave Wannstedt, but since 2002 and especially since 2004 have fallen on harder times, reaching the postseason only twice in the twelve seasons since, and during the mid-2000s, briefly intensified the Dolphins-Patriots rivalry, when Nick Saban, a former Bill Belichick assistant was hired as the Dolphins head coach in 2005 and when he nearly signed quarterback Drew Brees with the Dolphins the following year. In 2007, if not for their overtime victory over the Baltimore Ravens, would've suffered an imperfect season, a year before the Detroit Lions became the first team to go winless since the NFL expanded to a 16-game schedule. That same season, the Dolphins became the first team in NFL history to win their division following a 1-15 season, and until 2020, marked the last non-Patriot division title in the AFC East. Since 2000 (the last season they won a playoff game), the Dolphins made the postseason 3 times, but never progressed past the Wild Card round.
