Sailor Uranus (セーラーウラヌス, Sērā Uranusu?) is one of the central characters in the Sailor Moon metaseries. Her real name is Haruka Tenoh (天王 はるか, Ten'ō Haruka?, or Amara in the English anime), a masculine schoolgirl who can transform into one of the series' specialized heroines, the Sailor Senshi.

Haruka is one of the most famous "out" characters in anime fandom. Her masculine persona (by shōjo standards) is one of the standard archetypes in yuri.
