Leucostele terscheckii, commonly known as the cardon grande cactus or Argentine saguaro, is a large cactus native to South America and popular in cultivation.[2]

This species was first describe as Cereus terscheckii by Ludwig Georg Karl Pfeiffer was published in 1837.[4] Heimo Friedrich and Gordon Douglas Rowley placed the species in the genus Echinopsis in 1974.[3] The specific epithet terscheckii honors the court gardener Carl Adolph Terscheck of Japanisches Palais in Dresden.
