Jubei-chan: The Ninja Girl (十兵衛ちゃん, Jūbei-chan^?) is a Japanese anime action comedy television series created by Akitaro Daichi (Fruits Basket, Tsukikage Ran). Jubei-chan follows Jiyu Nanohana, a modern highschool girl and unwilling heir to the Yagyu Jubei school of swordsmanship. The series is recognized for its magical girl stylings, including a mystical artifact, the Lovely Eyepatch, that serves as the source of the heroine's power.

Jubei-chan comprises two television series. The Secret of the Lovely Eyepatch premiered April 5, 1999 and revolves around Jiyu Nanohana coping with her newly entrusted powers and responsibilities and the centuries-old feud between the Yagyu and Ryujoji schools. The Counter Attack of Siberia Yagyu premiered January 7, 2004. The second series introduces Freesia Yagyu, daughter of Yagui Jubei and self-proclaimed heir to the Lovely Eyepatch. The Counter Attack of Siberian Yagyu focuses on Jiyu and Freesia's developing friendship and subsequent rivalry.

The series was broadcast worldwide through Animax. The Secret of the Lovely Eyepatch was licensed in North America by Bandai Entertainment. The rights to The Counter Attack of Siberian Yagyu were held by Geneon Entertainment. Both series were licensed by Media Blasters in 2012. The series premiered on Toku in the United States on December 31, 2015.

The main conflict in The Secret of the Lovely Eyepatch (ラブリー眼帯の秘密〜, Raburii Gantai no Himitsu^?) is between the Yagyu Jubei and Ryujoji schools. The rivalry was seemingly ended 300 years before the events of the series, when Yagyu Jubei defeated the Ryujoji school champion. Dying from his wounds, Jubei told his loyal companion Koinosuke to find someone with "plump, bouncy bon bons" and give her his eyepatch that contained a lifetime's worth of sword techniques. Unknowingly to Koinosuke, the Ryujoji clan plots their revenge.
