The Island Archway was a 25 metre high, naturally formed rock arch that lay off Loch Ard Gorge, a bay on the south coast of Victoria, Australia.

The arch of rock exposed in the water has been frequently photographed by the numerous international and domestic tourists vacationing in the Great Ocean Road area.

The national and international press reported extensively on this geological event.

The Island Archway was part of a series of free-standing limestone formations on the Great Ocean Road that includes the Twelve Apostles.
