Cereus (/ˈsɪəriəs/ "serious") is a genus of cacti (family Cactaceae) including around 33 species of large columnar cacti from South America. The name is derived from Greek (κηρός) and Latin words meaning "wax", "torch" or "candle". Cereus was one of the first cactus genera to be described; the circumscription varies depending on the authority. The term "cereus" is also sometimes used for a ceroid cactus, any cactus with a very elongated body, including columnar growth cacti and epiphytic cacti.

Cereus are shrubby or treelike, often attaining great heights (C. hexagonus, C. lamprospermus, C. trigonodendron up to 15 metres or 49 feet). Most stems are angled or distinctly ribbed, ribs 3–14 centimetres (1+1⁄4–5+1⁄2 inches) long, usually well developed and have large areoles, usually bearing spines. Cephalium is not present; C. mortensenii develops pseudocephalium. The flowers are large, funnelform, 9–30 cm (3+1⁄2–11+3⁄4 in) long, usually white, sometimes pink, purple, rarely cream, yellow, greenish, and open at night. The fruits are globose to ovoid to oblong, 3–13 cm (1+1⁄4–5 in) long, fleshy, naked, usually red but sometimes yellow, pulp white, pink or red. The seeds are large, curved ovoid, glossy black.
