Cirrhilabrus ryukyuensis is a wrasse from the western Pacific Ocean from Indonesia, Malaysia and the Philippines north to Japan.

It occasionally makes its way into the aquarium trade.

It grows to a size of 15 cm in length.

[1] Some authorities regard this taxon as a synonym of Cirrhilabrus cyanopleura,[2] but Fishbase[1] and the Catalog of Fishes treat it as a valid species.

[3] This species was called Cirrhilabrus lyukyuensis but this is treated as a misspelling.
