Belchior (, born Antonio Carlos Belchior, October 26, 1946 – April 30, 2017) was a Brazilian singer and composer. He was one of the first MPB singers from the Brazilian northeast to reach mainstream success, in the early 1970s.
His album "Hallucination" is considered by many critics to be the single most influential album in the history of MPB, and one of the most important music albums ever published in Brazil.
