Cestrum is a genus of between 150-250 species of flowering plants in the family Solanaceae, native to warm temperate to tropical regions of the Americas, from the southernmost United States (Florida, Texas; C. diurnum) south to central Chile (Bío-Bío Region; C. parqui).

They are shrubs growing to 1-4 m tall, mostly evergreen, a few deciduous. All parts of the plants are toxic, causing severe gastroenteritis if eaten.
