The 2015 The Citadel Bulldogs football team represented The Citadel, The Military College of South Carolina in the 2015 NCAA Division I FCS football season.

The Bulldogs were led by second-year head coach Mike Houston and played their home games at Johnson Hagood Stadium.

Due to their head-to-head loss to Chattanooga, they did not receive the SoCon's automatic bid to the FCS Playoffs.

Ten starters returned on offense, with only QB Aaron Miller lost to graduation.

No players were named to national award watch lists or the preseason All-America teams, but OL Sam Frye and DL Mitchell Jeter were named to the preseason All-Conference first team.
