Ranking Dread (born Winston Brown, c.1955, died 1996) was a Jamaican reggae deejay who grew up in the Kingston ghettos of Rema and Tivoli. He became famous for his work with the Ray Symbolic sound system in the 1970s. He later lived a life of crime and died in a Jamaican prison.

Ranking Dread first became known as a deejay on the Ray Symbolic sound system in Jamaica, but by the late 1970s he had moved to London, where he worked with Lloyd Coxsone's sound system. He released four albums starting with Girls Fiesta in 1978, produced by Linval Thompson, and worked with producer Sugar Minott on his third album, Lots of Loving. He had a minor UK hit in the early 1980s with "Fatty Boom Boom", but in the mid-1980s, he faded from the music scene but became notorious for his criminal activities, and was labelled "the most dangerous man in Britain and the number one Yardie Godfather". This was backed up by his appearance on a British television programme in the late 1980s entitled The Cook Report. However, when interviewed by Ben Chin in 1990 for a Canadian TV documentary, he denied all allegations put to him.

He had been involved with Jamaican gang leader Claude Massop, and was wanted by Jamaican police in connection with over thirty murders. He travelled to the United Kingdom, where he lived under several aliases including Errol Codling, became the head of a Hackney drug-dealing and armed robbery gang, and was wanted by the police there in connection with rape, murder, prostitution, and dealing in crack cocaine. He was arrested at an illegal drinking club in 1988 and found to be in possession of illegal drugs and deported later that year, officially for entering the country illegally, after being branded the most dangerous foreign national living in Britain.[8] In 1990, after being deported from the United States, he was arrested in Canada for allegedly slashing his girlfriend's face with a knife after entering the country illegally on a fake passport, and attempted to gain refugee status there, claiming that he feared for his life in Jamaica due to his political affiliations.

He was eventually extradited back to Jamaica where he died in prison in 1996.
