The Amazonian trogon (Trogon ramonianus), is a species of bird in the family Trogonidae, the trogons and quetzals. It is found in Bolivia, Brazil, Colombia, Ecuador, Peru, and Venezuela.

Trogons have distinctive male and female plumages, with soft, often colorful, feathers. The Amazonian trogon is about 23 to 25 cm (9.1 to 9.8 in) long; three males weighed 44 to 46 g (1.6 to 1.6 oz). The male's head, neck, and upper breast are a deep metallic blue-black. The face and throat are black, with little contrast between them and the rest of the head. A narrow white band separates the upper breast from the bright yellow lower breast and belly. The upperparts are metallic green to blue-green. The tail's upperside is deep blue with black feather tips; the underside has fine black and white bars and broad white feather tips. The wings are mostly black with some whitish inclusions. The female's head and face, upper breast, and upperparts are dark gray; the belly is a duller yellow than the male's, and the underside of the tail has a different pattern of black and white. The two subspecies' plumages differ very little, with the differences between them being similar to those among individuals of each.
