Canada and northeastern United States, from central Alberta east to central Quebec south to northern Minnesota, Michigan, New York and Connecticut as well as along the Appalachians south to West Virginia; Western United States, from British Columbia and southwestern Saskatchewan south to southern California. Found in migration anywhere in the United States except rare in Montana, Wyoming and Florida.

Recent results indicate that the two subspecies may not be each others closest relatives (Virginia's Warbler intertwined).
