The Grammy Award for Best Male Rap Solo Performance was an honor presented to male recording artists at the 45th Grammy Awards in 2003 and the 46th Grammy Awards in 2004 for quality rap solo performances. The Grammy Awards, an annual ceremony that was established in 1958, and originally called the Gramophone Awards, are presented by the National Academy of Recording Arts and Sciences of the United States to "honor artistic achievement, technical proficiency and overall excellence in the recording industry, without regard to album sales or chart position".
