The first description as Cereus euphorbioides was in 1819 by Adrian Hardy Haworth. The specific epithet euphorbioides is derived from the Greek word -oides for 'similar' and the genus 'Euphorbia'. Nathaniel Lord Britton and Joseph Nelson Rose placed the species in the genus Cephalocereus in 1920. Further nomenclature synonyms are Cactus euphorbioides (Haw.) Spreng. (1825), Pilocereus euphorbioides (Haw.) Rümpler (1886), Lemaireocereus euphorbioides (Haw.) Werderm. (1934), Carnegiea euphorbioides (Haw.) Backeb. (1944), Neobuxbaumia euphorbioides (Haw.) Buxb.
