Jealousy is an EP by Japanese band Loudness. It was released in May 1988 only in Japan, a market that the band felt to have neglected in favour of American audiences. It would also mark the final recording with the classic line-up, until Spiritual Canoe in 2001. Singer Minoru Niihara left the band after the end of the domestic tour promoting this release. The song "Long Distance Love" would later be reworked for the On the Prowl album, with vocals by American singer Mike Vescera.
