Jejune is the name of a band which formed in 1996 at Berklee College of Music in Boston, Massachusetts. The band has been commonly identified with the emo genre, and was heavily involved with the scene at the peak of the "second wave" of emo in the mid-late 90's. The three founding members, Arabella Harrison (Bass/Vocals), Joe Guevara (Guitar/Vocals) and Chris Vanacore (Drums), met while studying at the college. The band relocated to San Diego, California, in 1997.

The band's earliest songs consisted of a more punk rock style, such as on their first single, "Drive by Negly". The band continued recording demos with the expectation of eventually recording their debut album, but ending up issuing a compilation of those demos as their first album, Junk, in 1997. A split single with Jimmy Eat World, including the song "Early Stars", was released in early 1998.
