Mari Iijima (飯島 真理), born May 18, 1963 in Tsuchiura, Ibaraki, Japan) is a Japanese singer-songwriter. She writes and produces most of her own music, is a multi-instrumentalist, including playing the piano. After being signed to JVC Victor in 1982, Mari first became known for her voice-acting role as Lynn Minmay in the anime Macross. Her debut original album, Rosé, was released in 1983, which was produced by composer Ryuichi Sakamoto. She also later collaborated with other world-renowned musicians, such as Van Dyke Parks. She lives in Los Angeles, California, United States.

Iijima's original demo tape was picked up by JVC Victor in 1982 and she was signed to the record company as a singer-songwriter. Soon afterward, she was asked to audition for the role of Lynn Minmay in The Super Dimension Fortress Macross by the label and the producers chose her to play the role. The series quickly became a mega hit and brought Iijima to stardom. Her debut album, Rosé, containing no Macross tracks, had lyrics and music written by her. It debuted at number 10 on the charts in September 1983, and she started her career as a singer-songwriter.

Iijima moved to Los Angeles in 1989 to expand her music career. That same year, she appeared as a guest vocalist on Van Dyke Parks' album Tokyo Rose. After releasing her first independent (and first English language) album, No Limit, she was nominated for the 2000 Los Angeles Music Awards' Best Pop Artist for the album and she was in the final four for the award.
