Red Rock is a Quaternary complex volcano in the Australian state of Victoria.

It is located 11 km (6.8 mi) northwest of the small city of Colac near the southeastern shore of Lake Corangamite.

The volcano is structurally complicated, consisting of a series of volcanic cones and maars.

[3] Red Rock, along with Tower Hill, Purrumbete and Leura, is one of the best preserved phreatomagmatic features in Eastern Australia.

[2][1] This makes Red Rock one of the Newer Volcanics Province centres to have been active during the Holocene epoch.
