The Antiochian Orthodox Archdiocese of Australia, New Zealand and the Philippines (Arabic: أبرشية أستراليا، نيوزيلندا والفيلبين للأرثوذكس الأنطاكيين) is an archdiocese of the Antiochian Orthodox Church, with headquarters in Sydney, Australia.

The canonical jurisdiction of the Metropolitan of Hong Kong and South East Asia which belongs to the Ecumenical Patriarchate of Constantinople does not recognize the claim of this diocese over the Philippine Islands which also canonically falls under the Metropolis of Hong Kong.

The Archbishop resides in Australia, there is a Deanery for New Zealand, and presences in other countries of the Pacific Ocean region.

The archdiocese formerly had a female monastery of Saint Anna in Preston, Victoria, Australia, but this has since closed and its monastic presence relocated to the Antiochian Village in Goulburn, New South Wales.

The archdiocese also founded the multi-jurisdictional Melbourne Institute of Orthodox Christian Studies.
