Adenochilus gracilis is a species of plant in the orchid family Orchidaceae and is endemic to New Zealand.

Its labellum has red to maroon bars and a central band of yellow calli, but is almost obscured by the dorsal sepal.

Adenochilus gracilis is a terrestrial, perennial, deciduous, herb with a long, thin, horizontal rhizome.

[2][3]Adenochilus gracilis was first formally described in 1853 by Joseph Dalton Hooker and the description was published in Flora Novae-Zelandiae.

[5] This orchid grows in thick layers of moss or partly decomposed leaf litter in scrub and forests.
