At the 1908 Summer Olympics in London, nine wrestling events were contested, all for men.

There were four weight classes in Greco-Roman wrestling and five weight classes in freestyle wrestling.

The number of classes in freestyle was reduced from 7 to 5, with the light fly, fly, and welterweight classes dropped but the middleweight added.

The addition of the 4 Greco-Roman classes brought the total number of events in wrestling up to 9.

Belgium, Bohemia, Germany, and the Netherlands also sent wrestlers, but did not win any medals.
