Mozart Camargo Guarnieri (February 1, 1907 Tietê, São Paulo – January 13, 1993 São Paulo) was a Brazilian composer.
He studied piano and composition at the São Paulo Conservatório, and subsequently worked with Charles Koechlin in Paris. Some of his compositions received important prizes in the United States in the 1940s, giving Guarnieri the opportunity of conducting them in New York, Boston, Los Angeles and Chicago. A distinguished figure of the Brazilian national school, he served in several capacities; conductor of the São Paulo Orchestra, member of the Academia Brasileira de Música, and Director of the São Paulo Conservatório, where he taught composition and orchestral conducting. In 1936 he was the first conductor of the Coral Paulistano choir. His œuvre comprises symphonies, concertos, cantatas, two operas, chamber music, many piano pieces, and over fifty canções.
