2015 Miami Dolphins season

The 2015 Miami Dolphins season was the franchise's 46th season in the National Football League and the 50th overall. The Dolphins looked to improve on their 8-8 record from 2014 and return to the playoffs for the first time in seven seasons. However, Miami failed to clinch a playoff berth for the seventh consecutive season after a Week 14 loss to the Giants.

The Dolphins entered 2015 with Joe Philbin as their head coach for a fourth season. After the team started 1-3, Philbin was fired by the Dolphins. Dan Campbell, the team's tight ends coach, served as the interim head coach for the remainder of the season and recorded a 5-7 record.
