Sérgio Santos Mendes (Brazilian Portuguese: [ˈsɛʁʒju ˈsɐ̃tus ˈmẽdʒis]; born February 11, 1941) is a Brazilian musician. He has over 55 releases, and plays bossa nova heavily crossed with jazz and funk. He was nominated for an Oscar for Best Original Song in 2012 as co-writer of the song “Real in Rio” from the animated film Rio.

Mendes is a unique example of a Brazilian musician primarily known in the United States, where his albums were recorded and where most of his touring took place.

Mendes is married to Gracinha Leporace, who has performed with him since the early 1970s. Mendes has also collaborated with many artists through the years, including The Black Eyed Peas, with whom he re-recorded in 2006 a version of his breakthrough hit “Mas Que Nada“.

Mendes was born in Niterói, Brazil, the son of a physician. He attended the local conservatory with hopes of becoming a classical pianist. As his interest in jazz grew, he started playing in nightclubs in the late 1950s just as bossa nova, a jazz-inflected derivative of samba, was emerging. Mendes played with Antônio Carlos Jobim (regarded as a mentor) and many U.S. jazz musicians who toured Brazil.
