Orchideae is a tribe of orchids in the subfamily Orchidoideae. Historically, it was divided into 2 subtribes, Orchidinae and Habenariinae. The subtribe Orchidinae alone contains about 1,800 species.[ However, although some Phylogenetics studies have established the monophyly of the subtribes, the generic boundaries are unclear, with many genera as traditionally circumscribed being Paraphyly or even Polyphyly.][ Species of genera such as Habenaria and Platanthera have been placed into both subtribes.][ A 2017 molecular phylogenetic study found that both subtribes did form clades, but did not formally recognize Habenariinae, because of missing genera and uncertainty over generic boundaries.][ The Asian species of Orchideae, in particular, have been subject to repeated changes of generic placement from 2012 onwards.][

As of 2017, Orchideae is divided into 6 subtribes: Brownleeinae, Pachitinae, Huttonaeinae, Orchidinae, Coryciinae, and Disinae.
