Kopsiopsis strobilacea, the California groundcone, is a species of parasitic plant in the family Orobanchaceae.{{r|powo|jp|usda}} It is native to California and southern Oregon, where it grows in wooded areas and chaparral. It is a parasite of Arbutus menziesii and inland manzanitas,{{Cite web |title=Kopsiopsis strobilacea - Flora of North America |url=http://beta.floranorthamerica.org/Kopsiopsis_strobilacea |access-date=2024-12-14 |website=beta.floranorthamerica.org}} which it parasitizes by penetrating them with haustoria to tap nutrients.{{Citation needed|date=July 2020}} The groundcone is visible aboveground as a dark purplish or reddish to brown inflorescence up to {{cvt|18|cm}} long. Pale-margined purple flowers emerge from between the overlapping bracts.{{r|jp}}

Formerly considered Boschniakia strobilacea, some taxonomists now place it in the genus Kopsiopsis on the basis of phylogenetic evidence.{{r|yu2013}} Morphological evidence indicates that this species may have exchanged genetics with Kopsiopsis hookeri in areas where their distribution overlaps.
