The opal-rumped tanager (Tangara velia ) is a species of bird in the family Thraupidae. It is found in the Amazon and Atlantic Forest of South America. The population of the Atlantic Forest has a far paler chest than the other populations, and has often been considered a separate species as the silvery-breasted tanager (Tangara cyanomelas ). Today most authorities treat it as a subspecies of the opal-rumped tanager.
