The 2015 Utah State Aggies football team represented Utah State University in the 2015 NCAA Division I FBS football season. The Aggies were led by third-year head coach Matt Wells and played their home games at Merlin Olsen Field at Maverik Stadium. This was Utah State's third season as members of the Mountain West Conference in the Mountain Division. They finished the season 6–7, 5–3 in Mountain West play to finish in a four-way tie for second place in the Mountain Division. They were invited to the Famous Idaho Potato Bowl where they lost to Akron.
The Aggies lost both their Defensive and offensive coordinators (DC Todd Orlando to Houston and OC Kevin McGiven to Oregon State)
Among notable player losses to graduation were S Brian Suite, LB Zach Vigil, DE B.J. Larsen, WR Ronald Butler, and OL Kevin Whimpey. Another notable loss was QB Darrel Garretson announcing that he would be transferring to Oregon State University.
On June 29, it was announced that Bruce "JoJo" Natson was released from the team for violation of unspecified team rules.[1]
On May 18, 2015, demolition began on the west side of Maverik Stadium to make way for a new concourse, press box, and luxury box complex. Construction lasted throughout the season, and as a result, the stadium's capacity was temporarily reduced.
