Bơi tại Thế vận hội mùa hè năm 1896 - 100 mét tự do nam giới

The men's 100 metre freestyle was one of the four swimming events on the Swimming at the 1896 Summer Olympics programme. The 100 metre freestyle race was the first of the swimming events. Ten swimmers entered the race. The two competitors from Austria-Hungary finished in the top two places, though no record distinguishes the places of the other eight competitors. Alfréd Hajós of Hungary beat Otto Herschmann of Austria by about half a metre, with the other swimmers far behind. The Hungarian flag was hoisted, but the band began to play the Austrian anthem (Gott erhalte Franz den Kaiser) until the Hungarian sang the Hungarian anthem (Himnusz).
