The 2013 Colorado Buffaloes football team represented the University of Colorado at Boulder during the 2013 NCAA Division I FBS football season.

Led by first-year head coach Mike MacIntyre, the Buffaloes played their home games on-campus at Folsom Field in Boulder and were members of the Pac-12 Conference.

Head coach Mike MacIntyre was hired after the firing of Jon Embree concluding the 2012 season.
