Adenomera aurantiaca, the orange-legged terrestrial nest-building frog, is a species of frog in the family Leptodactylidae. It is endemic to Brazil.
This frog lives in lowland rainforests that do not flood. Scientists have seen it between above sea level.
Scientists have seen these frogs in one protected place, Floresta Nacional de Itaituba II, along the Rio Jamanxim.
The IUCN classifies this species as least concern of dying out. However, some of the frogs live near the expanding town of Trairão, and small-scale agriculture has had a significant impact.
