Charles Gelbert (December 24, 1871 – January 16, 1936) was an American football player, nicknamed "the Miracle Man" because he did so much with so little. He was a four-year starter for the Penn Quakers, from 1893 to 1896, and played guard and end. During his time at Penn, the school's football teams won consecutive national champions with undefeated seasons in 1894 and 1895. He also earned All-American honors from Walter Camp in 1894, 1895, and 1896. He was elected to the College Football Hall of Fame in 1960. In 1912, Jack Kofoed, writing in the Philadelphia Record, named Gelbert to his all-time All-America team.
Gelbert also took part in gymnastics. It was said that his acrobatic play would help his defensive play in football when facing off against much larger men. Outside of football he worked as a veterinary surgeon in Scranton, Pennsylvania.
