The decathlon is a combined event in athletics consisting of ten track and field events. Events are held over two consecutive days and the winners are determined by the combined performance in all. Performance is judged on a points system in each event, not by the position achieved. The decathlon is contested mainly by male athletes, while female athletes typically compete in the heptathlon.

The Olympic decathlon is divided into a two-day competition, with the track and field events held in the order below. Traditionally, all decathletes who finish the event, rather than just the winner or medal winning athletes, do a round of honour together after the competition.
