The 2015 LSU Tigers football team represented Louisiana State University as a member of the Western Division of the Southeastern Conference (SEC) during the 2012 NCAA Division I FBS football season. Led by 11th-year head coach Les Miles, the Tigers finished the season with an overall record of 9–3 and mark of 5–3 in conference play, tying for third place in the SEC's Western Division. LSU was invited to the Texas Tech, where the Tigers defeated Texas Tech. The team played home games Tiger Stadium in Baton Rouge, Louisiana.

Offseason
LSU lost only three underclassmen to the NFL in the offseason: linebacker Kwon Alexander, cornerback Jalen Collins and defensive end Danielle Hunter; this was a large decrease compared to losing 11 underclassmen in 2012 and 7 in 2013. On January 16 Les Miles held a press conference announcing that six underclassmen starters would return, including leading receiver Travin Dural and star defensive back Jalen Mills, as well as offensive linemen Vadal Alexander and Jerald Hawkins, tight end Dillon Gordon, and linebacker Lamar Louis.

For the third consecutive season, LSU signed a top-ten recruiting class consisting of 25 signees, highlighted by top-rated recruits Kevin Toliver II, Arden Key, Tyron Johnson, and Donte Jackson. While not as acclaimed as the previous season's consensus #2 ranked class, the class was ranked #10 by ESPN, #8 by rivals.com, and #5 by 24/7 sports.

In 2023, all wins for the 2014 season were vacated by the NCAA.
