Chakotay /tʃəˈkoʊteɪ/ is a fictional character who appears in each of the seven seasons of the American science fiction television series Star Trek: Voyager. Portrayed by Robert Beltran, he is First Officer aboard the Starfleet starship USS Voyager. The character was suggested at an early stage of the development of the series. He is the first Native American main character in the Star Trek franchise. This was an intended move by the producers of the series, who sought to provide an inspiration as with Uhura in Star Trek: The Original Series for African Americans. To develop the character, the producers sought the assistance of Jamake Highwater. Despite first being named as a Sioux, and later a Hopi, Chakotay was given no tribal affiliation at the start of the series, something that was later resolved in the episode "Tattoo".
