Hystricidae (Old World porcupines)
Erethizontidae (New World porcupines)

Porcupines are rodents with a coat of sharp spines, or quills, that defend and camouflage them from predators. They are indigenous to the Americas, southern Asia, and Africa. Porcupines are the third largest of the rodents, behind the capybara and the beaver. Most porcupines are about 25–36 in (63–91 cm) long, with an 8–10 in (20–25 cm) long tail. Weighing between 12–35 lb (5.4–16 kg), they are rounded, large and slow. Porcupines come in various shades of brown, grey, and the unusual white. Porcupines' spiny protection resembles that of the unrelated erinaceomorph hedgehogs and monotreme echidnas.

The common porcupine is a herbivore. It eats leaves, herbs, twigs and green plants like skunk cabbage and clover and in the winter it may eat bark. The North American porcupine often climbs trees to find food. The African porcupine is not a climber and forages on the ground. It is mostly nocturnal, but will sometimes forage for food in the day. Porcupines have become a pest in Kenya and are eaten as a delicacy.

The name porcupine comes from Middle French porc espin (spined pig). A regional American name for the animal is quill pig.
