Junior Murvin (born Murvin Junior Smith, circa 1949, Port Antonio, Jamaica) is a Jamaican reggae musician. He is best known for the single "Police and Thieves", produced by Lee "Scratch" Perry in 1976. Murvin's soaring voice and the infectious rhythm made "Police and Thieves" into an international hit during the summer of that year. It peaked at #23 in the UK Singles Chart in 1980. The song was influential and it was recorded by the punk rock pioneers The Clash on their debut album, released in 1977. Australian musician Paul Kelly makes a reference to Murvin in his Christmas song, "How To Make Gravy".
