This small drab warbler breeds across Alaska and Canada and is much more common in the West than in the East. It passes through Tennessee on its way to and from the wintering grounds in the southern United States and Central America. It can be found in the state from mid-April to early May and again in late September to early November.

The head has an inconspicuous orange crown, a broken eye-ring, a dark line through the eye, and a thin pointed bill. It lacks wing-bars and tail-spots. Females and juveniles look similar but are even duller. Western birds are yellower than eastern birds.

The genus name for the Orange-crowned Warbler was changed from Vermivora to Oreothlypis in the summer 2010 by the American Ornithologists' Union, the authority on bird taxonomy in North America.
The Orange-crowned Warbler is divided into four subspecies across its breeding range that differ in plumage color, size, and molt patterns.
- The Orange-crowned Warblers breeding in the boreal forest of Canada have one of the latest fall migrations of any warbler, not leaving the breeding grounds until late September or October.
