Edward William "Eddie" Mahan (January 19, 1892 – July 22, 1975) was an American football player. While playing halfback for Harvard, Mahan was selected as a first-team All-American three consecutive years from 1913–1915. He was widely regarded as one of the greatest football players in the first 50 years of the sport and was named by Jim Thorpe as the greatest football player of all time. In 1951, he was elected to the College Football Hall of Fame as part of the first group of inductees.
