Hernán Cattáneo (Spanish pronunciation: [eɾˈnaŋ kaˈtaneo]; born 4 March 1965) is an Argentine house DJ.

Cattáneo began his professional career playing in the early 1990s for FM Z95, a local radio station largely responsible for the diffusion of electronic dance music in Argentina.

Paul was so impressed with his craft, that he asked Hernan to open for him on his tours globally.

Shortly thereafter, he signed to Paul Oakenfold's Perfecto Records, which later led him to become a Cream resident in Liverpool, England and Ibiza, Spain.

In May 2007, he released Sequential Volume 2, which was once again followed by another worldwide tour to promote the compilation.
