The trogons and quetzals are birds in the order Trogoniformes which contains only one family, the Trogonidae. Alternatively, they might constitute a member of the basal radiation of the order Coraciiformes (Johansson & Ericson, 2003). The word "trogon" is Greek for "nibbling" and refers to the fact that these birds gnaw holes in trees to make their nests.

Trogon is a genus of near passerine birds in the trogon family. Its members occur in the New World--see family account for details.
