Litoria gracilis, also known as the slender spotted 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 species is endemic to New Guinea. It is known from the foothills of the highlands of Papua New Guinea.
When breeding, the frog glue their eggs to leaves above water, presumably as protection from predators, with the tadpoles dropping into the water after emergence.
