Eduardo Mateo (1940–1990) was a Uruguayan singer, songwriter, guitarist, and arranger.
He played an important role in the development of modern Uruguayan music that combines beat, jazz, bossa nova and local rhythms like candombe in a way similar to Brazilian Tropicalismo.
Academy Award-winner Jorge Drexler cited Mateo as a big influence.
His songs have been performed by Pedro Aznar, Martin Buscaglia, Hugo Fattoruso, Fernando Cabrera, Leon Gieco, Mio Matsuda, Sandra Mihanovich, Milton Nascimento, Jaime Roos, and Tomohiro Yahiro.
