Ewoks were a diminutive primitive species of furry bipeds native to the forest moon of Endor. They were most notable for helping the Rebel Alliance defeat the forces of the Galactic Empire at the Battle of Endor, allowing the shield generator there to be destroyed, and in turn, the DS-2 Death Star II Mobile Battle Station.

Ewoks were individuals that stood about one meter tall. They used spears, slings, and knives as weapons; they also used hang gliders as vehicles. Although skilled in forest survival and the construction of primitive technology, the Ewoks had yet to progress past stone-level technology when discovered by the Empire. They were quick learners, however, when exposed to advanced technology with simple mechanical processes and concepts.

Ewoks were sentient humanoids, averaging about one meter in height. Omnivorous, they were covered in fur from head to toe, with brown and black as the most common colors. Most Ewoks had solid-colored fur, though a few sported stripes. Ewoks had large, bright eyes, small humanoid noses, and hands that possessed two fingers and an opposable thumb. Despite their small size, Ewoks were physically strong enough to overpower combat-trained humans.
