The American Redstart, Setophaga ruticilla, is a New World warbler. They breed in North America, across southern Canada and the eastern USA.

These birds are migratory, wintering in Central America, the West Indies, and northern South America. They are very rare vagrants to western Europe.

This species is unrelated to the Old World redstarts. This species derives its name from the male's red tail, start being an old word for tail.
