Ewok is a species in the Star Wars "universe"

They are sentient furred bipeds native to the forest moon of Endor. Although extremely skilled in forest survival and the construction of primitive technology like gliders and catapults, the Ewoks have yet to progress past stone-level technology. When the Empire began operations on the moon of Endor, they dismissed the primitive species as harmless. Imperial operations were situated around the area near the Ewok village led by Chief Chirpa. Princess Leia Organa, part of a Rebel strike team, befriended the Ewok Wicket W. Warrick, a scout from said village. These Ewoks mistakenly worshipped the protocol droid C-3PO, thinking he was a god. Threepio told the Council of Elders the adventures of the Rebel heroes Luke Skywalker, Princess Leia, and Han Solo. The Ewoks accepted the Rebels into their tribe, and allied themselves to their cause. The Ewoks helped in the ground battle to destroy the Imperial shield generator on the forest floor, and their primitive weapons felled the stormtroopers and the scout walkers of the Empire. This assist paved the way to victory at the Battle of Endor. Later that night, the Ewoks held a huge celebration in the forest.

Trivia

The rebel team was supposed to come across a lost tribe of Wookiees on Endor. For whatever reason this idea didn't pan out.

Though this species is known as Ewoks, they are never actually called that. In fact they are never called anything in The Return of the Jedi.
