Vanilloideae is one of the subfamilies of orchids belonging to the large family Orchidaceae.

But their single, incumbent anther and poorly organised pollinia led to their recognition as at best a subgroup of monandrous orchids.

The subfamily Vanilloideae consists of 15 genera and about 180 species, belonging to the tribes Pogonieae and Vanilleae.

The species in the tribe Pogonieae have a characteristic laciniate lip margin.

The color of their petals and sepals is pink or rarely white or bluish.
