Fred Kenelm Nielsen (April 22, 1879 – January 12, 1963) was a Danish-American lawyer, diplomatic official, and college football coach.

[5] He replaced its previous coach, D. John Markey, who had quit after the school denied an increase to the job's $300 salary.

[7] In his first year there, the Hatchetites posted a poor 2–5–1 record, but improved to 9–1–1 the following season, which was enough to clinch the South Atlantic Intercollegiate Athletic Association (SAIAA) championship.

[10] Georgetown's losses came at the hands of undefeated, untied, and unscored upon Pittsburgh and the Carlisle Indians led by Jim Thorpe.

[4] As the assistant solicitor, Nielsen did not intend to continue coaching, but in 1915, the Catholic University of America implored him to take over its ailing football program.

[14] Nielsen resigned from that position in 1922,[15] and later that year, President Harding nominated him as the American representative for the British-American Claims Commission.
