The emerald tanager is a species of bird in the tanager family Thraupidae. It is found in Colombia, Costa Rica, Ecuador, and Panama. Described by the English ornithologists PL Sclater and Osbert Salvin in 1869, it is a medium-sized species that has a length of 10.6–13 cm (4.2–5.1 in) and a mass of 18–20.5 g (0.63–0.72 oz). It can be identified by its bright green plumage, with black streaking on the back and wings, and a black auricular patch and beak. It also has yellow on the crown and rump.
