Scinax ruber is a species of frog in the family Hylidae. It is known in English as the red snouted treefrog or red-snouted treefrog, sometimes also Allen's snouted treefrog, the latter referring to the now-synonymized Scinax alleni. This widespread species is found in much of Amazonian and northern coastal South America and into Panama, as well as in some Caribbean islands as introduced populations. It is a complex containing several cryptic species.
