The 2018 season was the Miami Dolphins' 49th in the National Football League (NFL), their 53rd overall and their third and last under head coach Adam Gase. During the offseason, the Dolphins tweaked their uniforms' orange color 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 the 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 also the team's second consecutive losing season, with all 7 wins decided by one possession scores.
