The '''Orchidoideae''', or the orchidoid orchids, are a subfamily of the orchid family ([[Orchidaceae]]).

They typically contain the orchids with a single ([[monandrous]]), fertile [[anther]] which is erect and [[basitonic]].(producing no [[Leaf|leaves]] below the [[inflorescence]]).

The subfamily Orchidoideae and the previously recognized subfamily Spiranthoideae are considered the closest allies  in the natural group of the monandrous orchids because of 
* a shared [[terrestrial plant |terrestrial]] habit
* [[sectile]] (capable of being severed) [[pollinium|pollinia]]
*erect anthers.

The Orchidoideae contain two subclades  with the following tribes : 
* tribes [[Orchideae]] and [[Diseae]]
* tribes [[Cranichideae]] and [[Diurideae]]

The former subfamily Spiranthoideae is now embedded as tribe Cranichideae in the [[cladistics|clade]] of the Orchideoideae. It is sister to the tribe Diurideae.

The tribe Orchideae consists of the following subtribes:
* [[Habenariinae]]
* [[Orchidinae]]

The tribe Diseae consists of the following subtribes:
*[[Disinae]]
*[[Satyriinae]]

The polyphyletic tribe Cranichideae consists of the following monophyletic subtribes :
* [[Cranichidinae]]
* [[Goodyerinae]]
* [[Pachyplectroninae]]
* [[Prescottiinae]]
* [[Spiranthinae]]

The tribe Diurideae consists of the following subtribes : 
* [[Pterostylidinae]] (polyphyletic)
* [[Chloraeinae]] (polyphyletic)
* [[Acianthinae]] (monophyleric)
* [[Caladeniinae]] (polyphyletic)
* [[Cryptostylidinae]] (monophyletic)
* [[Diuridinae]] (monophyletic)
* [[Drakaeinae]] (monophyletic)
* [[Prasophyllinae]](monophyletic)
* [[Thelymitrinae]] (monophyletic)
