Ewoks were never referred to by name in the Star Wars movie.
Anybody who as seen Return of the Jedi knows what an Ewok is, but the term is never used in the film. The name only came out originally in promotional materials. The name Ewok came from the real Native American tribe Miwok, the natives of the area of California where they filmed the forest scenes. - (source)
