''Rubus boyntonii'', also called Boynton's dewberry, is a rare North American species of flowering plant in the Rosaceae, rose family. It has been found only in the States of Virginia and North Carolina in the east-central United States.
The genetics of ''Rubus'' is extremely complex, so that it is difficult to decide on which groups should be recognized as species. There are many rare species with limited ranges such as this. Further study is suggested to clarify the taxonomy. Some studies have suggested that ''R. boyntonii'' may have originated as a hybrid between ''Rubus allegheniensis, R. allegheniensis'' and ''Rubus flagellaris, R. flagellaris. ''
