Milton Nascimento (Portuguese pronunciation: [miwˈtõ nasiˈmẽtu]; born October 26, 1942, Rio de Janeiro, Brazil) is a prominent Brazilian singer-songwriter and guitarist.

Nascimento's mother was the maid Maria Nascimento. As a baby, Milton Nascimento was adopted by his mother's former employers: the couple Josino Brito Campos, a banker employee, mathematics teacher and electronic technician; and Lília Silva Campos, a music teacher and choir singer. When he was 18 months old, Nascimento's biological mother died, and he moved with his adopted parents to the city of Três Pontas, in the state of Minas Gerais.

Nascimento was an occasional DJ on a radio station that his father once ran. He lived in the boroughs of Laranjeiras and Tijuca in Rio de Janeiro.

In the early stages of his career, Nascimento played in two samba groups: Evolussamba and Sambacana. In 1963, he moved to Belo Horizonte, where his friendship with Lô Borges led to the Clube da Esquina ("corner club") movement. Members included Beto Guedes, Toninho Horta, Wagner Tiso, and Flávio Venturini, with whom he shared compositions and melodies. One composition was "Canção do Sal", which was first interpreted by Elis Regina in 1966 and led to a television appearance with Nascimento. The collective, as well as some others, released Clube da Esquina in 1972. Several hit singles were also released.
