Oscar François de Jarjayes (オスカル・フランソワ・ド・ジャルジェ, Osukaru Furansowa do Jaruje) is a fictional character created by Japanese manga artist Riyoko Ikeda.

Upon the completion of her military training at the age of fourteen, Oscar is tasked with protecting the Dauphine Marie Antoinette when she arrives at Versailles.

[7] Soon gaining the Dauphine and Queen-to-be's affection and trust, Oscar experiences life at Versailles and the pain caused by the contradictions of her being a woman whom everybody, including herself, considers a man.

[5] As violence erupts in Paris, Oscar renounces her status and her French Guards Regiment[8] joins forces with the people marching to the Bastille.

Modeled after the revolutionary Pierre-Augustin Hulin, Oscar was originally a supporting character to Marie Antoinette and was created as a female because Ikeda was unsure if she could accurately portray a male soldier.

[18] In the South Korean musical of La Rose de Versailles, Oscar played by Ock Joo-hyun, Kim Ji-woo and Jung Yoo-ji (U.Ji)[19] because most, if not all, large scale South Korean Musicals are generally double or triple cast for a role, the actresses share the role equally and alternate throughout the eight show week.

[5][23] Shamoon sees the Oscar-Andre relationship as very different from the Cinderella-Prince Charming stories which "dominated" shōjo manga in the 1960s, where the female protagonist would lose her identity to her boyfriend.

[24] Kazuko Suzuki says that after RoV, "several works" were created with "nonsexual" female protagonists like Oscar, who realise their "womanness" upon falling in love.

It was adapted into a six episode TV series and renamed Haken no Oscar ~"Shōjo Manga" ni Ai o Komete, which aired starting from 28 August 2009.
