Anthony Edwin "Ant" Phillips is an English musician, best known as a founding member of the band Genesis. He played guitar and sang backing vocals until leaving in 1970, following the release of their second album, Trespass. He left due to suffering from stage fright, after being told by his doctor that the best thing would be to leave the band. He is known for his twelve string guitar work, and his influence can be heard throughout Genesis's early output.

Genesis's first album after Phillips's departure, Nursery Cryme, featured two songs which were holdovers from the days when Phillips was in the band: "The Musical Box" and "The Fountain Of Salmacis." "The Musical Box" especially remains a favourite of fans, but few recognise Phillips's contribution to the composition.
