At the 1904 Summer Olympics of St. Louis, Missouri, eleven gymnastics events were contested for the first time.

[1] The 1904 Games had a program of events spread out over several months, and the gymnastics competition was no different.

The International Olympic Committee considers two sets of events as "Olympic": The individual all-around was a combination of the gymnastic triathlon competition and the athletics triathlon.

[2] The parallel bars, horizontal bar, vault, and pommel horse scores for each gymnast were summed to get the combined score.

119 gymnasts from 4 nations competed.
