Bokermannohyla alvarengai is a species of frogs in the family Hylidae.
It is endemic to Brazil. Its natural habitats are subtropical or tropical high-altitude grassland, rivers, and rocky areas. It is threatened by habitat loss.
Bokermannohyla alvarengai is able to lighten its skin colour when hot (and darken when cold), making the skin reflect more heat and so avoid overheating.
