Carlos Gustavo Bossio (born 1 December 1973) is a retired Argentine professional footballer who played as a goalkeeper.
Ironically nicknamed Chiquito ("little") due to his height of 1.94 metres, Bossio represented several teams, but achieved greater notability at Estudiantes and Lanús.
He was part of the Argentina national team between 1994 and 1996, winning the golden medal at the 1995 Pan American Games and the silver medal at the 1996 Summer Olympics.
