Sailor Moon, originally released in Japan as Pretty Soldier Sailor Moon (Japanese: 美少女戦士セーラームーン, Hepburn: Bishōjo Senshi Sērā Mūn) and later as Pretty Guardian Sailor Moon, is a Japanese superhero anime television series produced by Toei Animation. It is based on the manga of the same title written by Naoko Takeuchi that was published from 1992 to 1997 in Nakayoshi. Sailor Moon first aired in Japan on TV Asahi from March 7, 1992, to February 8, 1997, and was dubbed for release in various regions around the world, including North America, Southeast Asia, Greater China, Australia, Europe, and Latin America.

The series follows the adventures of the titular protagonist whose name is Usagi Tsukino, a middle school student who is given the power to become a Pretty Soldier. Joined by other Sailor Soldiers, she defends Earth against an assortment of evil villains. The anime also parallels the maturation of Usagi from an emotional middle school girl to a responsible young adult.

Following the success of the anime in the United States, the manga comprising its story was released there by Tokyopop. Sailor Moon's popularity has spawned numerous additional media based on its universe, including films, video games, and soundtracks. A second animated adaptation, Sailor Moon Crystal, which is a reboot series that more closely follows the manga, began streaming worldwide in July 2014.
