The men's 300 metre free rifle kneeling event was one of five free rifle events in shooting at the 1900 Summer Olympics in Paris.

The kneeling position was won by Konrad Stäheli of Switzerland, with Emil Kellenberger of Switzerland and Anders Peter Nielsen of Denmark tying for silver.

This was the only appearance of the men's 300 metre kneeling rifle event.

The Olympic event doubled as the 1900 world championship.
