Pacific-slope flycatchers winter in southern Mexico from the southern end of Baja California, along the coastal lowlands of the Pacific coast, to Oaxaca. They breed along the Pacific coast, from northern Baja California to southeastern Alaska. Their range stretches east to the Rocky Mountains in British Columbia, the Cascades in Oregon, and the Sierra Nevada mountains in California.
