The Nemean Games were one of the four Panhellenic Games of Ancient Greece, and were held at Nemea every two years.

With the Isthmian Games, the Nemean Games were held both the year before and the year after the Olympic Games and the Pythian Games in the third year of the Olympiad cycle. Like the Olympic Games, they were held in honour of Zeus. They were said to have been founded by Heracles after he defeated the Nemean Lion; another myth said that they originated as the funeral games of a child named Opheltes. However, they are known to have existed only since the 6th century BCE.

The winners received a wreath of wild celery leaves from the city of Argos.

The Society for the Revival of the Nemean Games was founded in 1994, after more than 20 years of archaeological excavation at Nemea. The contemporary games, held every four years since 1996, are a form of popular education in history, as well as a counter to the commercialism of the modern Olympics. Races are organized according to age and gender, open to international participation. No medals are awarded, only crowns of palm branches and wild celery.

In 2008, some 600 people clad in tunics raced barefoot in the ruins of the ancient stadium on June 21. Two races were staged for the runners aged from 10 to 80, one of 100 metres (110 yards) and the other of 7.5 kilometres. The most striking feature of this attempt was the revival of the Hoplitodromos race
