Jean-Michel Byron (born Jean-Michel Byron DuPlessis on 13 October) is a South African-born rockvocalist and lyricist, best known as the lead vocalist for Los Angeles rock band Toto for new material on their first greatest hits album, Past to Present, as well as the band's Greatest Hits Live...and More project. Originally from East London, South Africa, he attended high school (senior secondary) at John Bissicker High School in a former Coloured area. He sang at high school concerts and community shows.
Byron joined Toto for their Past to Present album, singing on the four new tracks: "Love Has the Power", "Animal", "Can You Hear What I'm Saying" and "Out of Love." During the supporting tour in 1990, Byron and the band began to clash. His on-stage antics and rumored diva-like behavior irked both band and fans alike, and Byron was quickly relegated to the role of backing vocalist by the band before being dismissed.
