2015 Tennessee Titans season

The  Tennessee Titans season was the franchise's 46th season in the National Football League, the 56th overall and the 19th in the state of Tennessee. Second-year head coach Ken Whisenhunt was fired on November 3 following a 1–6 start, and was replaced by tight ends coach Mike Mularkey on an interim basis. Despite slightly improving from their 2–14 season from the previous year, finishing with a 3–13 record (tied with the Cleveland Browns), they were statistically the worst team in the NFL for the season, thus earning the right to the top pick in the 2016 NFL Draft, later trading it to the Los Angeles Rams.

Uniform change
The Titans switched their primary colored jerseys from light "Titans Blue" to navy blue, the latter of which was the team's primary home jersey color from 1999–2007.
