Setophaga is a genus of birds of the New World warbler family Parulidae. It contains at least 34 species. For example, the males in breeding plumage are often highly colorful. The Setophaga warblers are an example of adaptive radiation with the various species using different feeding techniques and often feeding in different parts of the same tree.

The New World warblers or wood-warblers are a group of small, often colorful, passerine birds that make up the family Parulidae and are restricted to the New World. The family contains 120 species. They are not closely related to Old World warblers or Australian warblers. Most are arboreal, but some, like the ovenbird and the two waterthrushes, are primarily terrestrial. Most members of this family are insectivores.
