Their geographic range extends from southern Maine to northern Georgia and westward to central Kentucky and eastern Ohio. Their occupancy is dependent on the availability of large patches of open habitats.

Coluber constrictor constrictor ranges from Georgia, Alabama, and Mississippi in the south, to central New York, Vermont, New Hampshire, and Maine in the north, to Tennessee, Kentucky, and eastern Ohio in the west. At the southern end of its range, it overlaps with Coluber constrictor priapus, the southern black racer, and at the westward end it overlaps with Coluber constrictor flaviventris, the eastern yellow-bellied racer.

Upon hatching, the juveniles tend to have dark gray to reddish-brown dorsal patterns with a light gray to brown body that becomes occluded with age and the melanin becoming so abundant that all but the pale chin and brown snout are obscured.

They will inhabit urban and agricultural areas, barrier islands, and grasslands in mountains. The Northern black racer will seek refuge under objects like logs, rocks, and other debris during the night or on cool days.
