The Australian green tree frog, simply green tree frog in Australia, White’s tree frog, or dumpy tree frog (Litoria caerulea) is a species of tree frog native to Australia and New Guinea, with introduced populations in New Zealand and the United States. The species belongs to the genus Litoria.

The green tree frog is larger than most Australian frogs, reaching 10 cm (4 in) in length. The average lifespan of the frog in captivity, about 16 years, is long in comparison with most frogs. Green tree frogs are docile and well suited to living near human dwellings. They are often found on windows 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.

Its color depends on the temperature and colour of the environment, ranging from brown to green; the ventral surface is white. The frog occasionally has small, white, irregularly shaped spots on its back. At the end of its toes, it has large discs, which provide grip while climbing. The eyes are golden and have horizontal irises, typical of the Litoria genus.The fingers are about one-third webbed, and the toes nearly three-quarters webbed. The tympanum (a skin membrane similar to an eardrum) is visible.

Although frogs have lungs, they absorb oxygen through their skin, and for this to occur efficiently, the skin must be moist. A disadvantage of moist skin is pathogens can thrive on it, increasing the chance of infection
