Apollo Bay is a coastal town in southwestern Victoria, Australia. It is situated on the eastern side of Cape Otway, along the edge of the Barham River and on the Great Ocean Road, in the Colac Otway Shire. The town had a population of 1,095 at the 2011 Australian census.
It is now a tourist destination, though it is smaller and quieter than other nearby places such as Lorne. It is also host to the annual Apollo Bay Music Festival and the Great Ocean Sports Festival.
In winter to spring, southern right whales come to the area mainly to breed, to give birth their calves, and to raise them in the warmer, calm waters of South Australia during their migration season. Less frequently, humpback whales can be seen off the coast.
