Swimming at the 1908 Summer Olympics – Men's 100 metre freestyle
The men's 100 metre freestyle was one of six swimming events on the swimming at the 1908 Summer Olympics programme. It was the shortest of the three individual freestyle events, as the 50 yard freestyle had been dropped after its one appearance on the 1904 Summer Olympics programme. The 100 metre event was contested for the third time after it had been held at the 1896 and 1906 Olympics. The 1904 Olympics saw a 100-yard event. The competition was held on Friday 17 July 1908 and Monday 20 July 1908. Thirty-four swimmers from twelve nations competed. Each nation was limited to 12 swimmers.
