María Dolores Fernández Pradera OAXS MMT (29 August 1924[1] – 28 May 2018)[2][3] was a Spanish melodic singer and actress, and one of the most famous voices in Spain and Latin America.

As a singer, she specialized in traditional Spanish and Latin American music: bolero, copla, ballad, ronda, vals, and folk music (Peruvian, Argentine, Mexican, and Venezuelan).

Her contralto voice had a deep resonance and sure melodic footing which must stem from classical training.

She typically sang accompanied by guitars, requintos, and drums.

She sang for close to 30 years with the same group, Los Gemelos, formed by twin brothers, Santiago and Julián López Hernández, until the death of Santiago in the early 1990s.
