Philautus cardamonus is a species of frogs in the family Rhacophoridae.

It is endemic to Cambodia, only known from the vicinity of the type locality in the Phnom Sankos Wildlife Sanctuary in the Cardamom Mountains.

The skin of the dorsum is tan and dark brown in color.

The throat and chest have white and dark brown pigmentation.

Because this frog lives high in the hills, it might not be able to travel between fragmented habitats, especially when there has been extensive logging in the lowlands in between.
