Rubus armeniacus, the Himalayan blackberry or Armenian blackberry, is a species of Rubus in the blackberry group Rubus subgenus Rubus series Discolores Focke. It is native to Armenia and northern Iran, and widely invasive elsewhere. Both its scientific name and origin have been the subject of much confusion, with much of the literature referring to it as either Rubus procerus or Rubus discolor, and often mistakenly citing its origin as western European. Flora of North America, published in 2014, considers the taxonomy unsettled, and tentatively uses the older name Rubus bifrons.
