Glen Brown (born Glenmore Lloyd Brown, Jamaica), also known as 'God Son' and 'The Rhythm Master', is a Jamaican singer, musician, and record producer, working primarily in the genres of reggae and dub. He currently resides in New York.

Brown began his musical career in the 1960s as vocalist with Sonny Bradshaw's jazz group, subsequently recording duets with Hopeton Lewis, Lloyd Robinson and Dave Barker for producers such as Duke Reid and Coxsone Dodd. In the early 1970s he began working as a producer, initially for the Shalimar label, and recorded Augustus Pablo-influenced melodica tracks, such as 1972's "Merry Up". He also recorded for Prince Buster, Leslie Kong, and Derrick Harriott. He formed two record labels; Pantomime (or Pantomine), and South East Music, and produced tracks by U Roy, Gregory Isaacs, Big Youth, I-Roy, Prince Jazzbo, Johnny Clarke, Lloyd Parks, and Little Roy. Due to low funds, his early releases were pressed in limited runs, but have since become more widely available on various compilations, such as The Way To Mount Zion (featuring material from the 1969-1976 period), and Termination Dub (featuring material recorded with King Tubby between 1973 and 1979). Although he had fewer hits in the latter half of the 1970s, he maintained his profile with hits from the likes of Wayne Jarrett and Sylford Walker.

In 2000 Small Axe and Terminal Head remixed Brown's work for a single release that included remixes of fellow reggae artist, Yabby You. In 2002, Glen Brown's single produced by Ras Kush, "We Dem A Watch," was the first release on New York's Black Redemption label.
