Ferocactus hamatacanthus, commonly named Turk's Head, is a barrel cactus in the tribe Cacteae.

Ferocactus hamatacanthus forms to be solitary, usually a globular to oblong shape, and grows up to 60 centimetres (24 in).

The fruit of this species is thin and the flesh is very juicy and edible, reminiscent of kiwis in flavor.

[2] Accepted subspecies:[3] Ferocactus hamatacanthus is widespread in the Chihuahuan Desert of north-western Mexico in the states of Chihuahua, Coahuila, Durango, Nuevo León, and San Luis Potosi; and in New Mexico, and south-western Texas near El Paso growing in limestone crevices at elevations of 700 to 200 meters.

In 1922, Nathaniel Lord Britton and Joseph Nelson Rose reclassified the species into the genus Ferocactus.
