The wood warblers are distributed over almost all of the New World from Alaska and northern Canada to northern Chile and Argentina. More than 50 species breed within the central and eastern portions of North America from about the middle half of the United States to the southern half of Canada.

Many wood warblers are wide-ranging. The yellow warbler and common yellowthroat, for example, breed from coast to coast in North America, throughout the United States and well into Canada and Mexico. On the opposite end of the spectrum, the Kirtland's warbler (Dendroica kirtlandii) occupies a tiny breeding range in north-central Michigan.
