2018 Miami Dolphins season

The 2018 season was the Miami Dolphins' 49th in the National Football League, their 53rd overall and their third and last under head coach Adam Gase. During the offseason, the Dolphins tweaked their uniforms and shade of orange to better align with their classical past and history. For the second straight season, they also brought back their throwback uniforms from the Shula/Marino eras and wore them for three games.

With quarterback Ryan Tannehill playing for the first time since 2016, the highlight of Dolphins' season came during a memorable Week 14 win against division rival and defending back-to-back AFC champion New England Patriots, which prevented the Patriots from clinching the AFC East that week. However, the Dolphins would lose all of their remaining games and missed the playoffs for the second consecutive year. The 7–9 finish was their first since 2012 and also the team's second consecutive losing season, with all 7 wins decided by one possession scores and not winning a playoff game for the 17th straight year.

Schedule
Note: Intra-division opponents are in bold text.

Week 1: vs. Tennessee Titans
Due to two weather delays, the game lasted for 7 hours and 10 minutes, the longest game since the AFL–NFL merger in 1970. Coincidentally, wide receiver Danny Amendola met with former teammates Malcolm Butler and Dion Lewis. The three played for the New England Patriots from 2015 to 2018 and helped them win Super Bowl LI over the Atlanta Falcons.

Week 3: vs. Oakland Raiders
With the win, the Dolphins improved to 3–0, their first such start since 2013.

Week 4: at New England Patriots
With their first loss of the season, the Dolphins failed to earn their first 4–0 start since 1995, during the Dan Marino era and Don Shula's final year as the Dolphins' head coach.

Week 6: vs. Chicago Bears
A last-second field goal kick by Jason Saunders barely averted a tie and gave the Dolphins the win in overtime.

Week 10: at Green Bay Packers
This was the Dolphins' final meeting with the McCarthy/Rodgers-led Packers, as the Dolphins beat them only once, during the Packers' 2010 Super Bowl-winning season.

Week 16: vs. Jacksonville Jaguars
With the loss, the Dolphins were eliminated from playoff contention.

Week 17: at Buffalo Bills
This season finale marked the final games of players such as quarterback Ryan Tannehill, linebacker Cameron Wake, and head coach Adam Gase all in Dolphins uniforms.
