“Manhã de Carnaval” (“Carnival Morning”) is a song by Brazilian composer Luiz Bonfá and lyricist Antônio Maria. It appeared as a principal theme in the 1959 Portuguese-language film Orfeu Negro by French director Marcel Camus.

The song became one of the first Bossa Nova compositions to gain popularity outside Brazil. In the United States, the song is considered to be one of the most important Brazilian Jazz/Bossa songs that helped establish the Bossa Nova movement in the late 1950s. “Manhã de Carnaval” has become a jazz standard in the U.S., and is performed regularly by a wide variety of musicians around the world in its vocalized version or just as an instrumental one.
