The Theatre Olympics (Greek: Διεθνής Θεατρική Ολυμπιάδα) is a non-profit organisation that promotes theatrical exchange where dialogue between different theatremakers, irrespective of ideological, culture and language differences is encouraged.

Established in 1994 by an international committee led by Greek theatre director, Theodoros Terzopoulos, The Theatre Olympics originally had the subtitle "Crossing Millennia" to reflect the importance the organisation placed on connecting the past, present, and future of human cultural endeavours and to reflect the festival's aim to re-establish the importance of theatre in the cultural life of the twenty-first century.

The first official meeting of the International Committee of Theatre Olympics took place on 18 June 1994 in Delphi, Greece, however discussions between the members had been ongoing since 1989.

[2] The founding committee was a group of eight internationally renowned theatre directors: Theodoros Terzopoulos, Nuria Espert, Antunes Filho, Tony Harrison, Yuri Lyubimov, Heiner Müller, Tadashi Suzuki and Robert Wilson.

The festival's national organising committee usually consists of prominent representatives of the country's cultural life.
