In 1896, Frédéric Albert Constantin Weber first described this species as Echinocactus peninsulae. The name "peninsulae" originates from Latin, meaning "peninsula," in reference to the species' presence on the Baja California peninsula. Nathaniel Lord Britton and Joseph Nelson Rose transferred the species to the genus Ferocactus in 1922. ==References==
