The Pileated Parrot (Pionopsitta pileata), also known as the Red-capped Parrot (leading to easy confusion with the Australia Purpureicephalus spurius), is a medium-small species of parrot with a total length of about 22 cm (8½ in). It is found in or near Atlantic forest in south-eastern Brazil, far north-eastern Argentina, and eastern Paraguay. A local name in Paraguayan Guaraní is Cúiu Cúiu.

It is the type species of the genus Pionopsitta, which, until recently, included several other species. The plumage of the Pileated Parrot is overall green with bluish flight feathers, a faint brownish-maroon auricular patch (lacking in juveniles) and, in the male, a bright red forehead that extends down to just below the eyes. Unlike all other species previously placed in this genus, the Pileated Parrot does not have a contrasting brownish-olive chest, and recently it was established via mtDNA that it is indeed distinct enough for the others to be moved into a separate genus, Pyrilia, again making Pionopsitta monotypic.
