The peppered tree frog, (Litoria piperata) is a species of frog in the family Hylidae. It has a green back speckled with black, a cream-coloured belly and a dark stripe running from the shoulder. It is endemic to a very small area of the Northern Tablelands of New South Wales, Australia where it is known from five stream systems. It has not been observed in the wild since the 1970s, but a frog of very similar appearance has been observed in an area slightly further night, and it is not clear whether these are L. piperata or an outlying population of Pearson's green tree frog (L. pearsoniana). The International Union for Conservation of Nature has assessed the peppered tree frog's conservation status as being "critically endangered".
