Mattafix are a UK alternative hip hop duo, made up of Marlon Roudette and Preetesh Hirji. Their sound is a fusion of hip hop, soul, reggae and dancehall.

Their first full single, "Big City Life", released by EMI on 8 August 2005 was a considerable hit, managing a number 15 peak on the UK singles chart, a big feat for a UK R&B/hip-hop group, and topped the charts in Germany, the Czech Republic, Austria and other European countries.

Their third single, "Passer By" was released on 24 October 2005, missing the UK Top 75. The single preceded their debut album Signs of a Struggle, which was released a week later.

They use the word "Babylon" quite frequently.
