The men's ISSF Olympic trap was one of the shooting competitions in the shooting at the 1900 Summer Olympics events in Paris. It was held from Sunday, July 15 to Tuesday, July 17, 1900. Thirty-one athletes from four nations competed. Roger de Barbarin took gold, René Guyot silver, and Justinien de Clary bronze. There was a shoot-off between de Barbarin and Guyot, which de Clary did not compete in despite having scored the same as the other two in the main round.

Olympic Trap is a shooting sport discipline contested at the Olympic Games and sanctioned by the International Shooting Sport Federation. Usually referred to simply as "trap", the discipline is also known in the United States as international trap, bunker trap, trench or international clay pigeon. It is considered more difficult than most other trap versions in that the distance to the targets and the speed with which they are thrown are both greater.
