Crataegus pennsylvanica, known as the Pennsylvania thorn,[2] is a species of hawthorn native to Delaware, New York, North Carolina, Ontario, Ohio, and Pennsylvania,[2] that grows to about 8 m in height.

[2] The mature trees have few thorns.

[2] This species has often been confounded with C. mollis, but the two species have separate native ranges except for an area of overlap in northeastern Ohio.
