The red-necked tanager (Tangara cyanocephala) is a species of bird in the family Thraupidae. It is found in Brazil, Argentina, and Paraguay. Its natural habitats are subtropical or tropical moist lowland forest and heavily degraded former forest.
The red-necked tanager was first described by Philipp Müller in 1776 as Tanagra cyanocephala. It is mostly green with a black back and a blue head and throat. Plumage is described as "brilliant and varied, including areas of bright red, bright green, blue, and black." They can be observed in mixed-species flocks along with green-headed tanagers.
