Sixto Diaz Rodriguez (also known as Rodríguez or Jesús Rodríguez; born July 10, 1942) is an American folk musician in Detroit, Michigan. His career initially proved short lived, with two little-sold albums in the early 1970s and two Australian concert tours. Unknown to him, however, his work became extremely successful and influential in South Africa, and continued to retain a loyal following in Australia. According to the film-makers of the documentary about him, Searching for Sugar Man, at one time he was arguably more famous than Elvis Presley in South Africa, though he was mistakenly rumored there to have committed suicide.

In the 1990s, determined South African fans managed to find and contact him, which led to an unexpected revival of his musical career. This is told in the 2012 Academy Award–winning documentary film Searching for Sugar Man, which helped give Rodriguez a measure of fame in his home country.
