Shonen Knife is a Japanese pop-punk band formed in Osaka in 1981. Influenced by 1960s girl groups, pop bands, the Beach Boys, and early punk rock bands such as the Ramones, the band crafts stripped-down songs with simple yet unconventional lyrics sung both in Japanese and English.

The band has been credited with making "the international pop underground more international" by "opening it up to bands from Japan". They have also performed as a Ramones tribute band under the name the Osaka Ramones. Guitarist/singer Naoko Yamano is the only member to have remained with the band for its entire history; her sister Atsuko Yamano was a founding member and, after a long hiatus, returned to the band in 2016. They have released 22 studio albums; their most recent album Our Best Place was released in February 2023.

In the words of the Boston Globe, "something oddly spellbinding occurs when deceivingly silly lyrics are sandwiched between a buoyant guitar and a rapid-fire, pop-punk drum kit. Which perhaps explains why the Japanese female alternative rock/pop punk trio Shonen Knife is still singing songs about cookies, sushi, jelly beans, and, of course, banana chips."
