The Barron River is located on the Atherton Tablelands inland from Cairns in North Queensland, Australia. With its headwaters below Mount Hypipamee, the 165-kilometre-long river with a catchment area of approximately 2,138 square kilometres forms through run off from the Mount Hypipamee National Park, flows through Lake Tinaroo, and eventually empties into the Coral Sea between Machans Beach and Aeroglen.
The stocking of exotic sports fish into the river has led to a serious decline in the diversity and abundance of native fish.
A total of 63 species of fish have been found in the river, including the glassfish, barred grunter, Snub-nosed Garfish, Fly-specked hardyhead, Mouth almighty, Bigeye Trevally, Goby, Jungle Perch, oxeye herring, eastern rainbowfish, Bony bream, Spotted scat, Giant gudgeon, Freshwater Longtom and Seven-spot Archerfish.
