Roberto Pettinato (born December 15, 1955 in Buenos Aires) is an Argentine musician, journalist, and television presenter.
Pettinato's father, Roberto Sr., was a high-ranking corrections officer in the administration of Juan Perón. When a coup deposed Perón in 1955, he and his family took refuge in the embassy of Ecuador, where Roberto Jr. was born. After obtaining a safe conduct and leaving for Ecuador, the family lived in Peru and Chile until allowed to return to Argentina in 1966.
The younger Pettinato became involved in the Argentine rock scene of the late 1970s mostly as a journalist with the El Expreso Imaginario monthly magazine, which he directed from 1980 until its demise in 1982. In parallel, he was the on-and-off saxophonist for the 1980s band Sumo, led by Anglo-Italian Luca Prodan.
After Prodan's death and the band's dissolution, he started working in television together with Gerardo Sofovich, co-hosting La noche del Domingo in the early 1990s. Later on, he gained popularity by hosting Duro de acostar on Telefe, a midnight talk show modeled after David Letterman's. In the mid-1990s, he attained cult status by co-hosting post-midnight sports and showbiz show Orsai (a deformation of the football term off-side) with Gonzalo Bonadeo on one of Argentina's many sports cable channels.
As an actor, he took part in Primicias, a television series produced by Pol-Ka and broadcast by Canal 13.
He also hosted TV programs Mira quien canta, Todos al diván, Petti en vivo (Canal 9), Un aplauso para el asador (Canal 13), and the ironic Indomables (América TV) and Duro de Domar. In March, of 2009 he began Un Mundo Perfecto, a late-night talk show on (América TV).
Following the unexpected ending of Indomables due to a conflict between the production company PPT and América TV, the production renamed and moved the program to Canal 13, where Pettinato (as of October 2006) hosts Duro de Domar.
He has hosted since 2004 a FM radio morning show called El Show de la Noticia.
He has released a free jazz album named Free Jazz Musica Anticomercial, as Robert Pettinato & Now Free Jazz.
