Mercedes Valdés Granit (September 24, 1922 – June 13, 1996), better known as Merceditas Valdés, was a Cuban singer who specialized in Afro-Cuban traditional music. Under the aegis of ethnomusicologists Fernando Ortiz and Obdulio Morales, Valdés helped popularize Afro-Cuban music throughout Latin America. In 1949, she became one of the first female Santería singers to be recorded. Her recording career, which continued until her death in 1996, was especially prolific in the 1950s and 1980s.
