Chaco is the third studio album by the Argentine duo Illya Kuryaki and the Valderramas, released in 1995 by Gigolo Productions.

The disc includes sixteen tracks that were mastered in New York by Ted Jensen (regular contributor to Madonna).

«The disc offers a new mind in which there is no place for discrimination or oppression, hence the name : this is a province where Indians still inhabit this land.» (Télam, 26/10/95).

Crosses of hardcore rap, hip-hop and progressive rock, this album had five singles: "Abarajame", "Jaguar House", "Remisero", and two ballads that Dante Spinetta and Emmanuel Horvilleur sang separately: "Húmeda" and "Abismo", respectively.

In 2007, the Argentine edition of Rolling Stone ranked it 38th on its list of "The 100 Greatest Albums of National Rock".
