Coragulac is a rural locality in western Victoria, 9 km north-west of Colac. It is situated in an area with fertile soil and known as the Warrion Hills. The Red Rock lookout, above the hills, Lake Coragulac and Lake Corangamite, is about 2 km north-west of Coragulac. South-east of Coragulac there are stony rises, further evidence of volcanic activity in the Warrion Hills.
Coragulac was named after an Aboriginal word that is thought to describe a sandy creek.
