John Royce Mathis , known popularly as Johnny Mathis, is an American Grammy Award-winning singer of popular music.

One of the last in a long line of traditional male vocalists who emerged before the rock-dominated 1960s, Mathis concentrated on romantic jazz and pop standards for the adult contemporary audience through to the 1980s. Starting his career with a standard flurry of singles, Mathis was far more popular as an album artist, with several dozen of his albums receiving gold and platinum status and seventy-three making the Billboard charts to date. Mathis has sold more than 350 million records and albums.
