The green-backed trogon (Trogon viridis) is the largest of the yellow-bellied trogons, measuring 28.5 cm (11.2 in) in length. As is the case with most Trogons, they are strongly sexually dimorphic, the male having a dark blue iridescent head and breast, while the back is iridescent green. Underparts are orange to yellow, the wings black, vermiculated with white. He also has large tail tips finished off in white and an eye ring that is pale blue.

Female birds resemble the male, though they have a gray back, head, and breast, along with highly distinctive barring to the outer webs of each tail feather.
The song of the green-backed trogon consists of about 20 cow notes that start slow, but accelerate towards the end.
