Hemipilia joo-iokiana is a species of flowering plant in the family Orchidaceae, native to northern Korea and Japan (central Honshu).

[1] Hemipilia joo-iokiana is a herbaceous perennial growing from an ovoid tuber.

The inflorescence consists of a few flowers arranged loosely rather than in a dense spike.

[3] A molecular phylogenetic study in 2015 suggested that it formed a related group of species with H. alpestris, H. kiraishiensis, H. sichuanica and H. chusua and was not closely related to other Hemipilia species from Japan.

Hemipilia joo-iokiana is native to the north of Korea and to Honshu in Japan (the Chubu and Kanto regions).
