''Rubus vigoratus'' is an uncommon North American species of flowering plant in the rose family. It grows in Nova Scotia and Massachusetts. Nowhere is it very common. 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. vigoratus'' may have originated as a hybrid between '' R. flagellaris'' and '' R. hispidus.
