The Temple of Hera, or Heraion, is an ancient Archaic Greek temple at Olympia, Greece, that was dedicated to Hera, queen of the Greek gods. It was the oldest temple at Olympia and one of the most venerable in all Greece. It was originally a joint temple of Hera and Zeus, chief of the gods, until a separate temple was built for him. It is at the altar of this temple, which is oriented east-west, that the Olympic flame is lit and carried to all parts of the world. The torch of the Olympic flame is lit in its ruins to this day. The temple was built in approximately 590 BC, but was destroyed by an earthquake in the early 4th century CE.

Olympia, officially Archaia Olympia, is a small town in Elis on the Peloponnese peninsula in Greece, famous for the nearby archaeological site of the same name. This site was a major Panhellenic religious sanctuary of ancient Greece, where the ancient Olympic Games were held every four years throughout Classical antiquity, from the 8th century BC to the 4th century AD. They were restored on a global basis in 1894 in honor of the ideal of peaceful international contention for excellence.
