David John Archer (born November 5, 1982) is an American football coach and former player. He was most recently the head coach of the Cornell Big Red football team, from January 2013 until November 2023.^[1]

Archer played high school football at Union-Endicott High School in Endicott, New York, where as a senior he served as team captain was named a first-team New York State all-star. Archer was a three-year starter for the Big Red football team at Cornell University, serving as team captain during his senior season, before graduating with a degree in economics in 2005.^[2]

In 2006, while teaching fourth and eighth grades in Newark, New Jersey as part of Teach For America,^[3] Archer was an assistant coach at Fairleigh Dickinson–Florham, before returning to Cornell as an assistant.

In January 2013, Archer was appointed as Cornell's head coach. At just 30 years old, Archer was the youngest head college football coach in NCAA Division I at the time of his appointment.^[2] Archer took over a team that had not managed a winning season since 2005.

The Big Red managed just five wins in Archer's first three seasons. Results started to improve in 2016, highlighted by Cornell's first away win against a ranked opponent since 1950 when the team overcame a 23-point deficit to defeat No. 25 Colgate. However, the Big Red could not get over the hump, managing just one .500 season in Archer's ten seasons in charge and never managing more than three Ivy League wins in a season.

Following the 2023 season, Cornell athletics director Nicki Moore announced that Archer would not return to the head coaching role for the 2024 season. Archer was the longest-tenured head coach at Cornell since George K. James (1947–60).^[1][4]
