Acriopsis, commonly known as chandelier orchids or 合萼兰属 (he e lan shu){{cite web |last1=Chen |first1=Xinqi |last2=Wood |first2=Jeffrey James |title=Acriopsis |url=http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=100328 |publisher=Flora of China |access-date=9 January 2019}} is a genus of flowering plants in the family Orchidaceaes. Orchids in this genus are epiphytic herbs with spherical or cylindrical pseudobulbs, creeping, branched rhizomes, thin white roots, two or three leaves and many small flowers. The flowers are non-resupinate with the lateral sepals joined along their edges and have spreading petals and a three-lobed labellum. The column has projections that extend hood-like beyond the anther.

The genus was first formally described in 1825 by Carl Ludwig Blume who published the description in Bijdragen tot de flora van Nederlandsch Indië.{{cite book |last1=Blume |first1=Carl Ludwig |title=Bijdragen tot de flora van Nederlandsch Indië (Part 7) |date=1825 |location=Batavia |pages=376–377 |url=https://www.biodiversitylibrary.org/item/9224#page/94/mode/1up |access-date=6 January 2019}} The name Acriopsis is derived from the Ancient Greek words akris meaning "locust" or "grasshopper"{{cite book|last1=Brown|first1=Roland Wilbur|title=The Composition of Scientific Words|date=1956|publisher=Smithsonian Institution Press|location=Washington, D.C.}}{{rp|68}} and opsis, meaning "having the appearance of" or "like",{{rp|483}} referring to the grasshopper-like shape of the column."

Orchids in the genus Acriopsis are found in India, Yunnan, Southeast Asia, New Guinea, Melanesia, Micronesia and Queensland. They grow mainly in low, humid rainforests, sometimes ascending to medium altitudes. Their roots have specialised roots which grow from them up through the air and make branches which feed on litter and other debris.Jones, David L. (2006).
