2015 Colorado State Rams football team

The 2015 Colorado State Rams football team represented Colorado State University during the 2015 NCAA Division I FBS football season. The Rams were led by first-year head coach Mike Bobo and played their home games at Sonny Lubick Field at Hughes Stadium. They were members of the Mountain Division of the Mountain West Conference. They finished the season 7–6, 5–3 in Mountain West play to finish in a four way tie for second place in the Mountain Division. They were invited to inaugural Arizona Bowl where they lost to fellow Mountain West member Nevada.

The Rams and Wolf Pack are both members of the Mountain West Conference. However, they are in opposite divisions and did not play each other in the regular season in 2015. This is the first time teams from the same conference have met in a non-championship bowl game since the 1979 Orange Bowl.
