Litoria haematogaster, also known as the red-bellied tree frog, is a species of frog in the subfamily Pelodryadinae. It was described in 2023 by Australian herpetologist Stephen Richards and his colleagues Stephen Donnellan and Paul Oliver. The specific epithet haematogaster comes from the Greek haema (‘blood’) and gaster (‘belly’), with reference to the frog's bright red abdomen.{{cite web |url= https://www.abc.net.au/news/science/2023-04-14/bird-poo-frog-five-new-species-papua-new-guinea-png/102207720|title= 'Bird poo' frog among five new species classified in Papua New Guinea|author= Nick Kilvert |date=2023-04-14|website= ABC Science|publisher=Australian Broadcasting Corporation |access-date=2023-04-30}}
