Octávio Pinto (São Paulo, November 3, 1890 – São Paulo, October 31, 1950) was a Brazilian composer and architect.
He was married to Guiomar Novaes, a major figure among twentieth-century Brazilian pianists.
Pinto was not a professional musician, but rather an architect who carried out business across Brazil.
In his youth, however, he took lessons with the famous Hungarian-French pianist Isidor Philipp, who taught Guiomar Novaes while she studied at the Paris Conservatoire, and wrote several pieces for solo piano until his death in 1950.
His best-known and most-performed music comes from his Scenas Infantis (Childhood Scenes), a suite composed in 1932 for his wife, who performed the suite and brought attention to her husband's work.
Pinto was well-known in Latin American music circles even before marrying Novaes.
He was also a close friend of Heitor Villa-Lobos, the best-known composer of Brazilian classical music of the twentieth century.
