The Meredith Music Festival is a three-day outdoor music festival held every December at the "Supernatural Amphitheatre", a natural amphitheatre located on private farmland near the town of Meredith in Victoria, Australia. A self-funded, non-commercial event that was first held in 1991, the festival spawned Golden Plains, a music festival that takes place over the Labour Day long weekend in March.

An amphitheatre or amphitheater is an open-air venue used for entertainment, performances, and sports. The term derives from the ancient Greek ἀμφιθέατρον, from ἀμφί, meaning "on both sides" or "around" and θέατρον, meaning "place for viewing".
