Petticoat Creek is a small coastal locality in the Shire of Colac Otway, Victoria, Australia.

[2] In the 2011 census, the population of Petticoat Creek was too low to report separately; however in November 2014 the Victorian Electoral Commission recorded two enrolled voters in Petticoat Creek, living in two properties.

[3][4] The locality reportedly derives its name from the family of a settler, Henry Mutlow Biddle, who had eight daughters who used to hang their petticoats to dry out by the creek that ran past their house.

[6] The beach at Petticoat Creek is dominated by a rock platform, but with enough sand behind it for sunbathing and picnicking.

Surf Life Saving Australia states that the area is "a very hazardous section of coast" for swimming.
