The Australian green tree frog (Ranoidea caerulea), also known as simply green tree frog in Australia, White’s tree frog, or dumpy tree frog, is a species of tree frog native to Australia and New Guinea, with introduced populations in the United States and New Zealand, though the latter is believed to have died out. It is morphologically similar to some other members of its genus, particularly the magnificent tree frog (R. splendida) and the white-lipped tree frog (R. infrafrenata).

Larger than most Australian frogs, the Australian green tree frog reaches 10 cm (4 in) or more in length. Its average lifespan in captivity, about 16 years, is long compared with most frogs. Docile and well suited to living near human dwellings, Australian green tree frogs are often found on window sills or inside houses, eating insects drawn by the light. The green tree frog screams when it is in danger to scare off its foe, and squeaks when it is touched.

Due to its appearance and behavioural traits, the green tree frog is a popular exotic pet throughout the world. The skin secretions of the frog have antibacterial and antiviral properties that may prove useful in pharmaceutical preparations and which have rendered it relatively immune to the population declines being experienced by many species of amphibian. It is a common species and the International Union for Conservation of Nature has assessed its conservation status as being “least concern“.
