Shiritsu Ebisu Chugaku

 are a Japanese female idol group. The band's name is officially shortened to . The group was created by 3B Junior, the third section of the talent agency Stardust Promotion. Shiritsu Ebisu Chugaku is considered a "little sister" group to another Stardust Promotion girl group, Momoiro Clover Z.
Shiritsu Ebisu Chugaku is named after a fictitious school in Ebisu, a neighborhood in Shibuya, Tokyo. It was planned as a group of elementary and middle school students. However, this concept has changed as the members aged. All of the current members have already graduated high school, and the group currently uses "Forever a Middle-schooler" as their concept.
The group was officially nicknamed "King of the School Play", and was advertised as being a group with very rough singing and dancing skills. Or, more accurately, the group's slogan at the time was "Unarticulated dance and shaky vocals." However, the group has outgrown said slogan over time, and have since reached a point where they're praised for their vocal skills. Originally formed as a quintet on August 4, 2009, the lineup has changed multiple times since then, with some members having "changed school" (the group's official term for leaving it) and some having "transferred in" (joined). The most recent lineup change occurred on May 5, 2021 when 3 new members were integrated into the group.
