Aldir Blanc (born Aldir Blanc Mendes, on September 2, 1946) is a Brazilian author of crônicas (journalistic vignettes, chronicles) and lyricist.
He co-composed many songs with singer-songwriter João Bosco, guitarist Guinga, and others.
Elis Regina recorded several of his songs, most notably "O bêbado e a equilibrista".
Another song of his is "Resposta ao tempo" (with lyrics by Cristovão Bastos), a ballad that became one of Nana Caymmi's most famous songs, and which was recorded by many other musicians thereafter, amongst them Milton Nascimento and Aldir Blanc himself.
