Rhythm Masters is a house music duo comprised of deejays Robert Chetcuti and Steve Mac, a.k.a. Steve McGuinness. They began mixing together around 1993 after meeting in Malta, doing remixes for, among others, Todd Terry, Michael Jackson, INXS, Junior Vasquez, David Morales, and Roger Sanchez.

In 2001 they released a full-length album entitled Disconnect Your Head on Tommy Boy Records's Silver Label, and scored two club hits in the US: "Ghetto", featuring Jo Watson (#10 Dance/Club Play) and "The Underground" (#6 Dance/Club Play).
