Raorchestes menglaensis (Zhishihe's bubble-nest frog or Mengla small treefrog) is a species of frog in the Rhacophoridae family. Only known from its type locality, Zhishihe in Mengla County, it is endemic to Yunnan, China, although it is expected to occur more widely, including adjacent Laos. Raorchestes menglaensis are small frogs: males measure only 16 mm (0.63 in) in snout-vent length, whereas females are slightly larger at 20 mm (0.79 in) SVL. It is a very rare species known from fewer than 10 specimens. It inhabits streamside shrubland. It is threatened by habitat loss.
