Porfiado (English: Obstinate) is the thirteenth studio album by Uruguayan rock band El Cuarteto de Nos, released on April 27, 2012, through Warner Music Argentina.

[5][6] It was produced by long collaborator Juan Campodónico, mixed and recorded by Julio Berta in Montevideo, Uruguay, and mastered by Tom Baker in Los Angeles, United States.

The name of the album, "porfiado" ("obstinate" in English), relates to the obsessive characters that appear throughout the songs as well as the themes of vengeance, like in the song "Buen día Benito", about the obsession of a man with a former classmate he wants to take revenge on, and obstination, which appears in "Algo mejor que hacer", that features the lines "seré un quedado pero acá me quedo, y no intenten alterar mi estado" ("I might be an idle but here I stay, and don't try to alter my state").

[5][6] Mainly an alternative rock album, Porfiado also features various genres of music such as ska in "Algo mejor que hacer", hip hop in "Cuando sea grande" and cumbia in "Enamorado tuyo".

[5] Luis Paz from Argentine newspaper Página 12 wrote that "with this album, the band closes a trilogy started by Raro and Bipolar, characterized by the sound power and Roberto Musso's capacity for special and very personal lyrics".
