The Guianan Red-Cotinga (Phoenicircus carnifex) is a species of bird in the Cotingidae family, the cotingas. It is one of two species in the genus Phoenicircus.

It is found in northeastern South America in the Guianas in Guyana, Suriname and French Guiana; also a small border region of adjacent eastern Venezuela. In Brazil the species is found in the lower Amazon Basin bordering the Guyanas at the Amazon River outlet, and only ranges upstream in the Braziliam states of Pará, and Amapá. It is found on Marajó Island and southwards into northeastern Pará.

Its natural habitat is subtropical or tropical moist lowland forests.

There is a minor intersecting of the Guianan Red-Cotinga range with the only other species in Phoenicircus, the Black-necked Red-Cotinga.
