Stenocereus is a relatively small genus of columnar or tree like cacti from the Baja California peninsula and other parts of Mexico, Arizona in the United States, Costa Rica, and Venezuela. It has, however, been enlarged by the addition of species from several other genera.

The flowers are mostly borne near the apex of the stems and mostly noctunal. They are considered easy to grow and generally grow slowly.

Stenocereus thurberi (the Organ Pipe Cactus ) is a well known member of this genus and is widely distributed in Arizona and northern Mexico.
