Nathan Troy Calhoun (born September 26, 1966) is an American football coach and former player. He is the head football coach at the United States Air Force Academy, a position he has held since the 2007 season.
After graduating from the United States Air Force Academy in 1989, Calhoun served on the Air Force coaching staff under Fisher DeBerry as a graduate assistant during the 1989–90 seasons. After serving out his military commitment, he went on to serve as the Falcons' recruiting coordinator and the junior varsity offensive coordinator over the 1993–94 seasons.
In 1995, he moved to Ohio University where he served as the quarterbacks coach for two seasons, and was promoted to offensive coordinator in 1997. During his first season with Ohio, his offense had measurable success, particularly in a game against Eastern Michigan, in which the school totaled 612 yards, second most in school history. The team also captured a win against Maryland in 1997, which was Ohio's first victory over a school from the Atlantic Coast Conference (ACC). The following week, Ohio fell three points short of defeating Kansas State. In Calhoun's final year at Ohio in 2000, the offense set a school record with 418.1 yards per game and rushed for a school-best 3,553. The Bobcats also ended the season with wins over two bowl teams, Minnesota and Marshall.
Calhoun became offensive coordinator and quarterbacks coach of Wake Forest University in 2001. During Calhoun's second season, the Demon Deacons led the ACC in total offense with 408.1 yards per game, with a league-best 990 plays and only 16 turnovers.
Calhoun began his NFL career with the Denver Broncos as a defensive assistant in 2003, and later moved to offense and special teams. When Broncos offensive coordinator Gary Kubiak was hired as the Texans' head coach, Kubiak brought Calhoun along and made Calhoun his offensive coordinator and quarterbacks coach. Calhoun finished out the 2006 season with the Texans before taking over at Air Force.

Calhoun was hired on December 22, 2006, to be the head football coach for Air Force, replacing DeBerry who retired after 23 years as the Falcons' head coach. In his first season as head coach of the Falcons, he took the team to a 9–3 record, and a spot in the Armed Forces Bowl against Cal. On December 4, 2007, Calhoun was named Mountain West Coach of the Year for 2007.[3]
