"Blue Hearts Theme" (ブルーハーツのテーマ, Burū Hātsu no Tēma) was the fourth single by the Japanese band The Blue Hearts. Though it was released after their major debut, it was written before they signed with a major label. It was released as a "double A-side" track on July 1, 1988, with "Chernobyl" (チェルノブイリ), a controversial single that was included with the release. Lyrics and music were written by Hiroto Kōmoto, the band's lead vocalist, and was arranged by The Blue Hearts. It was not included in any albums other than compilation albums. The track is 9 minutes 17 seconds in length.
