Rubus multifer is a North American species of dewberry in section Procumbentes of the genus Rubus, a member of the rose family. It is commonly known as Kinnikinnick dewberry or fruitful dewberry. It is rare or under-documented in most of its range extending from Minnesota to Maine and Virginia, except for the St. Croix River Basin and surrounding sandy regions of Minnesota and Wisconsin, where it is locally common.[http://bonap.net/MapGallery/County/Rubus%20multifer.png Biota of North America Program 2014 county distribution map]Bailey, Liberty Hyde 1943.

In Minnesota, Rubus multifer is listed as a State Special Concern species, growing in remnant prairies, oak savannas, meadows, and openings in woods dominated by oak (Quercus) and quaking aspen (Populus tremuloides). It colonizes a variety of habitats created through natural and anthropogenic disturbance, such as long-term canopy openings and borders shaped by fire or wind, railroad rights-of-way, utility corridors, and abandoned agricultural fields. In most cases, the native prairie or woodland vegetation is retained to some degree. The soils are invariably sandy and acidic, often dry and to a lesser degree mesic or moist.[https://www.dnr.state.mn.us/rsg/profile.html?action=elementDetail&selectedElement=PDROS1K4H0 MNDNR Rare Species Guide]{{Cite book |last=Smith |first=Welby R. |title=Trees and Shrubs of Minnesota: The Complete Guide to Species Identification |publisher=University of Minnesota Press |year=2008 |isbn=9780816640652 |pages=476-477}}
