Rubus blanchardianus (Blanchard's dewberry) is a rare North American species of flowering plant in the rose family. It has been found only in the State of Vermont in the northeastern United States.Biota of North America Program 2014 county distribution mapBailey, Liberty Hyde. 1923.

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.Flora of North America, Rubus Linnaeus, 1754. Bramble
