Stenocereus (from Ancient Greek στενός (stenós) 'narrow' and Latin cereus 'candle') is a genus of columnar or tree-like cacti from the Baja California Peninsula and other parts of Mexico, Arizona in the United States, Colombia, Costa Rica, Guatemala, Venezuela and the West Indies. The genus has been enlarged by the addition of species from several other genera. A close relative is the peculiar chinoa or chende cactus, Polaskia chende.
