Midori (ミドリ) was a four-member jazz-punk fusion band formed in 2003 in Osaka, Japan featuring Mariko Gotō on vocals and guitar, Yoshitaka Kozeni on drums, Keigo Iwami on bass, and Hajime on keyboard.

Gotō often wore a serafuku while performing, and would climb speakers and crowd surf. The band initially formed to play covers of kayokyoku, but decided they weren't talented enough, and began to write their own songs. As they developed their influences included Italian prog, Kodo, J-pop duo Judy & Mary and Janis Joplin.Their disbandment was publicly announced by Gotō on December 25, 2010, with their last show titled "Sayonara, Gotō-san" being played on December 28.

As a band, Midori released three albums, three extended plays, and two demos.
