Rhacophorus viridis (Okinawan tree frog) is a species of frog in the Rhacophoridae family. It is endemic to Ryukyu Islands, Japan. It is known from Amamioshima, Kakeromajima, Ukejima, Yoronjima and Tokunoshima islands of the Amami Group, and Okinawajima, Iheyajima and Kumejima islands of the Okinawa Group.
Two subspecies are distinguished: Okinawa green tree frog (Rhacophorus viridis viridis) of the Okinawa Group and Amami green tree frog (Rhacophorus viridis amamiensis) of the Amami Group.
Rhacophorus viridis is no longer present on Yoronjima island. Its disappearance from the island some time after 1958 is attributed to habitat change (conversion of paddy fields to drier habitats) and an introduced predator, Japanese weasel (Mustela itatsi). This is the first island-level extinction of a native amphibian in the Ryukyu Archipelago during modern times.
Rhacophorus viridis is a moderate-sized rhacophorid frog (snout-vent length 65–84 mm (2.6–3.3 in)). It is a common species in forests close to paddy fields and wetlands. It breeds in wetlands and paddy fields by larval development.
