Cereus repandus (syn. Cereus peruvianus), the Peruvian apple cactus, is a large, erect, spiny columnar cactus found in South America. It is also known as giant club cactus, hedge cactus, cadushi (in Papiamento and Wayuunaiki), and kayush.

Cereus repandus is grown mostly as an ornamental plant, but has some local culinary importance. The Wayuu from the La Guajira Peninsula of Colombia and Venezuela also use the inner cane-like wood of the plant in wattle and daub construction.
