The Ryukyu Robin (Erithacus komadori) is a bird endemic to Japan, restricted to the Ryūkyū Islands. It is sometimes placed in the genus Luscinia, but recent research suggests that the East Asian robins belong into a new genus uniting them with some East Asian Luscinias such as the Siberian Blue Robin (Seki, 2006).

The specific name komadori is, somewhat confusingly, the common name of its relative Erithacus akahige in Japanese.
