Zhangixalus smaragdinus (common names: Nepal flying frog, Günther's tree frog, giant treefrog, and others) is a species of frog in the family Rhacophoridae found in southwestern China (Yunnan, Tibet), north-eastern India, Nepal, western Thailand, and northern Vietnam, and possibly in Bangladesh.

[4] Zhangixalus smaragdinus lives in lowland to submontane moist evergreen forests.

It lays eggs in foam nests built above pools and ponds.

Outside the breeding season it is arboreal and lives high in the canopy.

In India, people occasionally catch this frog as subsistence food.
