Dryadorchis is a genus of flowering plants from the orchid family, Orchidaceae. It is endemic to New Guinea.
The stems are very short, and they bear subfalcate leaves. The racemose inflorescences have a swollen rhachis. They produce short-lived flowers with a long, slim column, which houses four pollinia. The unspurred labellum has a concavity in its centre.
The genus name of Dryadorchis refers to Dryad, a tree nymph or tree spirit in Greek mythology.
Dryadorchis grows epiphytically at elevations of 0-1700 m above sea level.
It was proposed to merge this genus with Sarcochilus and Thrixspermum, which however was rejected.
