Aganisia Lindl. 1839, is a small South American genus in the orchid family (Orchidaceae), subfamily Epidendroideae.

The genus was named after the Greek word ‘agnos’ (gratitude), perhaps referring to the sweet scent of its flowers.

These dwarf, epiphytic climbing orchids occur in n montane or savanna forests and alongside rivers in Trinidad, Brazil, Colombia, Venezuela, Guyana, and Peru.

These orchids show pseudobulbs and small flowers produced from a creeping rhizome. These flowers generally reach 4 cm in width. Their color is rare among orchids, varying from a rose-tinted violet to a blue-tinted violet. The flowers shows a short column foot and an elongate stipe.

They are rarely cultivated.
