Shiritsu Ebisu Chugaku, officially shortened to "Ebichu" (エビ中), is a female idol group formed in August 2009. It was created by 3B Junior (now known as Stardust Planet), a section of Stardust Promotion. Originally intended as a collective of elementary and middle school performers, it has evolved into the theme of "Forever a Middle-schooler" as the members have aged.

Ebichu was created as a quintet, from which the only remaining member is Rika Mayama. After its independent debut, the group made its official signing with Defstar Records in 2012. They transferred to SME Records in 2015.

As of May 2021, there are nine members in the group.
