Atahualpa Yupanqui (Spanish pronunciation: [ataˈwalpa ʃuˈpaŋki]; born Héctor Roberto Chavero Aramburu; 31 January 1908 – 23 May 1992) was an Argentine singer, songwriter, guitarist, and writer. He is considered the most important Argentine folk musician of the 20th century.

Yupanqui was born Héctor Roberto Chavero Aramburu in Pergamino (Buenos Aires Province), in the Argentine pampas, about 200 kilometers away from Buenos Aires. His father was a mestizo descended from indigenous people, while his mother was born in the Basque country. His family moved to the Northwest city of Tucumán when he was nine. In a bow to two legendary Incan kings, he adopted the stage name Atahualpa Yupanqui, which became famous all around the world.

In his early years, Yupanqui traveled extensively through the northwest of Argentina and the Altiplano studying the indigenous culture. He became politically active and joined the Communist Party of Argentina. In 1931, he took part in the failed Kennedy brothers uprising against the de facto government of José Félix Uriburu and in support of deposed president Hipólito Yrigoyen. After the uprising was defeated, he was forced to seek refuge in Uruguay. He returned to Argentina in 1934.
