Shōjo, shojo, or shoujo manga (少女漫画, shōjo manga^?) is manga marketed to a female audience roughly between the ages of 10 and 18. The name romanizes the Japanese 少女 (shōjo), literally "little female". Shōjo manga covers many subjects in a variety of narrative and graphic styles, from historical drama to science fiction — often with a strong focus on human and romantic relationships and emotions. Strictly speaking, shōjo manga does not comprise a style or a genre per se, but rather indicates a target demographic. Examples include Cardcaptor Sakura, Fruits Basket, Fushigi Yuugi, Ouran High School Host Club, Pretty Cure, Princess Ai, Princess Tutu, Revolutionary Girl Utena, Romeo x Juliet, Sailor Moon, Skip Beat, Shugo Chara!, Tokyo Mew Mew, Vampire Knight, and Nana (manga).

Japanese magazines specifically for girls, known as shōjo magazines, first appeared in 1903 with the founding of Shōjo kai (少女界^?, Girls' World), and continued with others such as Shōjo Sekai (少女世界^?, Girls' World) (1906) and the long-running Shōjo no tomo (少女の友^?, Girls' Friend) (1908).
