La voz de la zafra (translation, "the voice of the harvest") is the debut album by Argentine singer Mercedes Sosa.

It was recorded in 1961 and released in 1962 on the RCA Victor Argentina label.

Eight of the songs were composed by Armando Tejada Gómez and Manuel Óscar Matus, Sosa's husband.

[4] The Argentine Ministry of Culture wrote that La voz de la zafra and her second album Canciones con fundamento "established her on the Latin American scene not only because of the quality of her voice and her singing but also because of her enormous social commitment as founder of the Movimiento del Nuevo Cancionero.
