Nyctimystes narinosus, the common big-eyed treefrog, is a species of frog in the subfamily Pelodryadinae of the family Hylidae.

The tympanum is small but distinct,[2][5] partly obscured by the prominent supratympanic fold.

The palpebral reticulum forms an irregular broken network of brown lines.

There is a varying amount of cream to bright orange decoration consisting of scattered blotches and broad dorsolateral bands that reach the lores; this color may occasionally cover the entire dorsum.

[1][5] It is a high-altitude species, being found at elevations of 1,500–2,500 m (4,900–8,200 ft) above sea level[1] or higher.
