The guira tanager (Hemithraupis guira) is a species of bird in the family Thraupidae.

Taxonomy
The guira tanager was formally described in 1766 by the Swedish naturalist Carl Linnaeus in the twelfth edition of his Systema Naturae under the binomial name Motacilla guira. Linnaeus based his description on the "Guira-guaça beraba" that had been described by the German naturalist Georg Marcgrave in 1648 in his Historia Naturalis Brasiliae. The specific epithet guira is a Guaraní word meaning "bird". The type locality is the state of Pernambuco in eastern Brazil. The guira tanager is now placed in the genus Hemithraupis that was introduced in 1851 by the German ornithologist Jean Cabanis.
