Ferocactus emoryi is spherical or cylindrical solitary barrel cactus, light green to glaucous, reaching a diameter of 60–100 centimetres (24–39 in) and a height of 2–2.5 metres (6 ft 7 in–8 ft 2 in). It has 15 to 30 ribs with tubercles, especially in the juvenile stage. The spines are white to reddish. The central spine is very strong, 4–10 cm long, while the seven to twelve radial spines reach lengths of up to 6 cm. The large and funnel-shaped flowers are usually red or yellow, reach lengths of up to 7.5 centimeters and have a diameter of 5 to 7 centimeters. The fruit is ovoidal, about 5 cm long.


This species is found in nature in Mexico (Sonora, Sinaloa and Baja California Sur) and in the United States (Arizona).
