Joseph Cotton aka Jah Walton (born Silbert Walton, 1957, St. Ann, Jamaica) is a reggae deejay active since the mid-1970s.

After spending a year working in the Jamaican police force, Walton turned to recording, initially working with Joe Gibbs in 1976, under the name Jah Walton. He then moved to Harry Mudie, recording popular tracks such as "Stay a Yard and Praise God", "Touch Her Where She Want It Most" (the title track from his debut album), and "Married To A Bank Cashier". In the mid-1980s he began recording under the name Joseph Cotton, immediately having success in the United Kingdom with "No Touch The Style", leading to a television appearance on Channel 4's Club Mix programme in 1987. Several more reggae chart hits followed in the form of "Things Running Slow", "Pat Ha Fe Cook", "Tutoring", "Judge Cotton", and "What Is This". Walton continued to perform and record into the 1990s and 2000s.
