The 2021 Air Force Falcons football team represented the United States Air Force Academy as a member of the Mountain Division in the Mountain West Conference (MW) during the 2021 NCAA Division I FBS football season. Led by 15th-year head coach Troy Calhoun, the Falcons compiled an overall record of 10âÂÂ3 with a mark of 6âÂÂ2 in conference play, sharing the MW's Mountain Division title with Utah State. By virtue of a head-to-head loss to the Aggie, Air Force was left out of the Mountain West Championship Game. The Falcons were invited to the First Responder Bowl, where they defeated Louisville. The team played home games at Falcon Stadium in Colorado Springs, Colorado.
The preseason poll was released on July 21, 2021. The Falcons were predicted to finish in third place in the MW Mountain Division.
